▼ T-joints are common in beam-column connections of steel frames, vierendeel girders and at mid-span of N-trusses. Strengthening the members of these structures increases the demand on the joints, which may require joint strengthening. This thesis examines different strengthening techniques of T-joints of RHS members. In Phase I, the effectiveness of through-wall steel bolts is examined. This is accomplished by controlling the web outward buckling of the chord under the brace axial load. The study examined the effect of the number and pattern of bolts, as well as the web height-to-wall thickness (h/t) ratio of the chord, on strengthening effectiveness. Rectangular 203x76x(3.09, 4.5, and 5.92) mm chord members were tested. The 8 mm diameter steel bolts varied from a single bolt to 15 bolts of various distributions. The joint strength increased by 3.1%, 6.2%, and 29% for chords with (h/t) of 34, 45, and 65, respectively. The number and distribution of bolts had little effect on their effectiveness. In Phase II, similar T-joint specimens were strengthened using adhesively bonded GFRP plates, 9.5 mm thick, of different configurations, and 2 mm thick high-modulus CFRP plates of equivalent stiffness. It was shown that strength gain increases significantly, from 9% to 38%, as (h/t) ratio of the HSS chord increases from 34 to 65. In thin-walled HSS (h/t = 65), retrofitting provided significant gains in strength but not in ductility. In thick-walled HSS (h/t = 34), retrofitting provided little strength gain, but enhanced ductility, especially with properly bonded plates extending on the brace. Generally, plates fractured under local bending or delaminated within plate layers while bond was fully intact. In Phase III, selected configurations of the two retrofitting methods were used in additional T-joints with chord (h/t) ratio of 65, to study their effectiveness in presence of axial compression load in the chord. Two sustained load levels were induced in the chord, representing 45% and 80% of its full axial capacity. The transverse brace load was then gradually increased to failure. The through-wall steel bolts increased the joint capacity by 13% to 25%, depending on the chord’s axial load level, while the bonded GFRP plate increased the capacity by 38 to 46%.

▼ Existing power management systems are hard-wired, slow, unreliable and insecure. By improving the communication framework for power management systems, using Internet and modern communication protocols like IEC61850, Zigbee (IEEE 802.15.4), etc., not only can energy be managed better, but also, the system as a whole can be made faster, secure and reliable. Any communication network has certain important characteristics like delay, range, scalability, network topology, etc., that dictate its effectiveness and usefulness in a particular environment. Delays in various parts of the network is one of the important characteristics that needs to be studied carefully. Network delays can be reduced by not only faster hardware but also better software. Importance also needs to be placed on monitoring power consumption of the devices, and ways to improve power efficiency of the system. In conjunction with that, a first generation communication framework for renewable energy distribution and management system, was set up using a network of embedded boards and personal computers. Various communication protocols and interfaces were tried to prove the versatility and reliability of the entire system. Experiments were conducted to test the range and delays in various parts of the communication network. Having established a platform for the nodes to communicate, investigation was done to implement techniques that could make the nodes more power efficient. One of the ways to stretch the battery life is through addition of an SMPS. However, addition of an SMPS introduces power instability to the system and interferes with normal functioning of sensitive devices like ADC, compass, etc. A processor controlled SMPS was added to the communication platform and its interference with normal functioning of the system was studied. Possible hardware and software approaches to counter this interference are also presented. Advisors/Committee Members: Dr. Alexander Dean, Committee Chair (advisor), Dr. Frank Mueller, Committee Co-Chair (advisor), Dr. Eric Rotenberg, Committee Member (advisor).

▼ A migração entre os profissionais de saúde Portugueses, e mais concretamente, entre os Enfermeiros, constitui uma problemática já confirmada quer na comunicação social, quer interrogando os próprios profissionais, tendo-se transformado, tal como refere BUCHAN (2007), num tema central de debate sobre a política de saúde à escala mundial. Por outro lado, a população Europeia, considerada como a mais envelhecida a nível mundial, é motivo de grande preocupação. Devido a este envelhecimento, estima-se que irá haver uma maior prevalência de doenças crónicas entre a população e serão os enfermeiros os principais cuidadores responsáveis por dar resposta a esta problemática. Contudo, e devido às necessidades destes profissionais nalguns países com escassez de enfermeiros, houve uma globalização das práticas de enfermagem, criando-se fluxos migratórios. Assim, os enfermeiros são formados num país de origem e vão exercer a sua atividade num país de acolhimento, facto que corresponde ao conceito de brain drain ou ‘fuga de cérebros’, que consiste na saída de profissionais altamente qualificados do seu país de origem, onde se formaram, para um país de acolhimento, onde irão utilizar as competências adquiridas num universo laboral mais atrativo e com mais opções disponíveis. Neste estudo optou-se por uma metodologia qualitativa, tendo sido constituída uma amostra não probabilística de enfermeiros que se encontram, atualmente, a exercer a sua profissão noutro país da Europa. Esta amostra foi obtida através do sistema de amostragem por bola de neve, tendo sido os enfermeiros submetidos a uma entrevista semiestruturada. Pretendíamos envolver, não apenas, alguns dos motivos de emigração dos enfermeiros portugueses para outro país da Europa, como também, identificar e compreender as características pessoais deste grupo de profissionais que os incitaram a tomar essa decisão. Por sua vez, os fatores que impediriam a partida para o país de acolhimento e os fatores que impulsionariam o regresso foram, igualmente, importantes no nosso estudo, uma vez que queríamos obter alguns dados que permitissem, num futuro próximo, colaborar na elaboração de políticas de recursos humanos que permitissem reter estes profissionais em Portugal Foram abordados os principais motivos para emigrar relacionados com a vida profissional, com a estabilidade e segurança financeira, a proximidade com experiências migratórias, a proximidade cultural, os dividendos da experiência migratória e, ainda, com a possibilidade de uma nova experiência de vida. Estes resultados por um lado, suportam a informação teórica obtida antes da realização das entrevistas e, por outro complementam os dados já existentes sobre esta temática.

▼ Astyanax scabripinnis é uma espécie encontrada na Região Neotropical, essa espécie forma demes populacionais isolados em cabeceiras de riachos. Ela é taxonomicamente mal resolvida, mas se apresenta como interessante modelo para o estudo da presença de cromossomos B. A ocorrência desses cromossomos em A. scabripinnis pode estar associada a diversos fatores ambientais e populacionais, embora seja pouco esclarecido sobre a manutenção parasítica ou possíveis efeitos heteróticos desses cromossomos. A biologia reprodutiva relacionada à presença de cromossomo B em A. scabripinnis nunca foi abordada. Assim, foi objeto deste trabalho investigar se aspectos do processo reprodutivo, fundamental para o valor adaptativo, podem estar relacionados à presença de cromossomos B em A. scabripinnis. As coletas foram realizadas trimestralmente entre os anos de 2012 e 2013 na região de Campos do Jordão, São Paulo, Brasil (2240`49,5S, 4523`31,9 W), no Córrego da Fazenda Lavrinha, bacia do rio Paraíba do Sul. As gônadas foram classificadas macro e microscopicamente segundo estádios de desenvolvimento. Estabeleceu-se sazonalmente a proporção sexual da população nas diferentes amostragens. Foi calculada a relação gonadossomática (RGS) e a relação hepatossomática (RHS) separadamente para fêmeas com e sem cromossomo B. A presença de cromossomos B foi confirmada por meio da citogenética clássica e molecular com o emprego de sonda específica do cromossomo B construída por microdissecção cromossômica e amplificação por Degenerated Oligonucleotids Primers (DOP-PCR) e posterior hibridação fluorescente in situ (FISH). Análises de morfometria geométrica foram realizadas separadamente para fêmeas e machos com e sem a presença de cromossomos B. Os resultados indicam que a proporção sexual variou sazonalmente havendo um aumento do número dos machos em relação às fêmeas. Foram encontrados indivíduos hermafroditas na frequência de 7,7%. O período reprodutivo é caracterizado por um pico de reprodução atípico no período do inverno, além do período padrão observado a partir da primavera no mês de setembro. A presença de cromossomos B foi relacionada a possíveis estratégias reprodutivas distintas na população estudada, especialmente em relação ao aporte energético e estádios de desenvolvimento gonadal. Há diferenças morfométrica tanto entre indivíduos fêmeas e machos como entre indivíduos com e sem cromossomo B.

▼ Η υποβάθμιση της ποιότητας των υδάτων στην Ευρώπη οδήγησε το Ευρωπαϊκό Κοινοβούλιο στην έκδοση της Οδηγίας 2000/60/ΕΚ, σύμφωνα με την οποία τα επιφανειακά ύδατα πρέπει να βρίσκονται σε μια «κατάσταση που χαρακτηρίζεται καλή, τόσο από οικολογική όσο και από χημική άποψη».

Ο Αλφειός είναι ο μεγαλύτερος σε μήκος (112 km) και παροχή (ετήσιο δυναμικό 2100×106 m3 ύδατος) ποταμός της Πελοποννήσου και βρίσκεται στην πέμπτη θέση των μεγαλύτερων σε μήκος ποταμών που έχουν το σύνολο της ροής τους εντός του ελληνικού εδάφους. Η λεκάνη απορροής του, έκτασης 3.600 km2, βρίσκεται στη Δυτική και Κεντρική Πελοπόννησο. Οι κυριότεροι παραπόταμοί του είναι ο Ερύμανθος, ο Λούσιος και ο Λάδωνας. Στόχος της συγκεκριμένης ερευνητικής εργασίας είναι η εκτίμηση της ποιότητας και του βαθμού τροποποίησης των ποτάμιων ενδιαιτημάτων του Αλφειού και των παραποτάμων του από ανθρώπινες δραστηριότητες. Σε πρώτη φάση, η προσέγγιση της περιγραφής της δομής των ρεμάτων και ποταμών και της αναγνώρισης των ενδιαιτημάτων τους, έγινε με τη βοήθεια της αναγνωρισμένης μεθόδου RHS (River Habitat Survey). Ταυτόχρονα εφαρμόστηκε η μέθοδος QBR (Qualitat del Bosc de Ribera), ώστε να επιτευχθεί μια πιο ολοκληρωμένη εικόνα της οικολογικής ποιότητας των υπό μελέτη περιοχών. Στη συνέχεια, έγινε εκτίμηση των φαινομένων διάβρωσης/απόθεσης στην κοίτη και τις όχθες, με έμφαση στις περιοχές όπου εντοπίζονται ανθρώπινες παρεμβάσεις και επιχειρήθηκε η σύνδεσής τους με τα αποτελέσματα των προαναφερθέντων μεθόδων. Με την ανάλυση και επεξεργασία των δεδομένων εντοπίσθηκαν: οι πιέσεις που δέχονται οι ποταμοί, η ποιότητα της δομής και ο βαθμός τροποποίησης των ενδιαιτημάτων τους, οι σημαντικότερες περιοχές ως προς την οικολογική ποιότητα των ποταμών, καθώς και πιθανές περιοχές προς αποκατάσταση. Τα αποτελέσματα του RHS αναφορικά με την ποιότητα των ενδιαιτημάτων και ειδικότερα με τη σπανιότητα των χαρακτηριστικών, έδειξαν ότι στα εξετασθέντα υδάτινα σώματα δεν είχαμε συχνές τεχνικές παρεμβάσεις στην ενεργό κοίτη, με εξαίρεση τα φράγματα στις περιοχές Φλόκα και Λάμπεια. Σύμφωνα με τη βαθμολογία που προέκυψε από την επεξεργασία του πρωτόκολλου QBR, επιβεβαιώνεται ότι, η ποιότητα και το εύρος της παραποτάμιας ζώνης εξαρτάται περισσότερο από την παρουσία ή μη ανθρώπινων παρεμβάσεων, παρά από τα γεωμορφολογικά χαρακτηριστικά της περιοχής. Γενικότερα, τα αποτελέσματα της μελέτης έδειξαν πως η διακύμανση της υδρομορφολογικής κατάστασης είναι ανάλογη των πιέσεων που δέχονται οι ποταμοί, στις επιμέρους παραμέτρους (όχθες, παρόχθια ενδιαιτήματα κ.λπ.). Ως προς τα φαινόμενα απόθεσης και διάβρωσης στο μέσο και κάτω ρου του Αλφειού, σύμφωνα με τα δεδομένα του Corine, μέσα σε μια δεκαετία μειώθηκε το εύρος της κοίτης του ποταμού κατά 730 km2, δηλαδή κατά 7,2%. Πρόκειται για το τμήμα του ποταμού που δέχεται τις… Advisors/Committee Members: Γιαννόπουλος, Παναγιώτης, Androutsopoulou, Aggeliki, Τηνιακού, Αργυρώ, Παπαστεργιάδου, Εύα, Γιαννόπουλος, Παναγιώτης.

▼ Multi-scale problems in numerical electromagnetics are becoming increasingly common with the advent and widespread usage of compact mobile phones, body area networks, small and nano antennas, sensors, high-speed interconnects, integrated circuits and complex electronic packaging structures, to name just a few commercial applications. Numerical electromagnetic modeling and simulation of structures with multi-scale features is highly challenging due to the fact that electrically small as well as large features are simultaneously present in the model which demands for discretization of the computational domain such that the number of degrees of freedom is very large, thus, levying a heavy burden on computational resources. The multi-scale nature of a given problem also exacerbates the challenge of generating very fine meshes which do not introduce instabilities or ill-conditioned behaviors. In this work we introduce a hybrid technique, which combines frequency domain and time domain techniques in a manner such that the fine features (electrically small) of the object being modeled are handled by the Method of Moments (MoM) technique while the electrically large parts of the structure are dealt with by using the Finite-Difference Time-Domain (FDTD) technique in order to reduce the computational burden. Recently, structures with multi-scale features have been simulated by using the dipole moment (DM) approach combined with the FDTD technique to handle fine features in a multi-scale geometry. However, when the size of the scatterer becomes larger in terms of the wavelength and the quasi-static assumption becomes invalid, extensive modifications of the DM/FDTD hybrid approach are needed resulting in a high computational cost. The research proposes a novel hybrid FDTD technique, which combines the Method of Moments and the Finite-Difference Time-Domain techniques directly in the time domain circumventing the need to carry out frequency transform calculations as required in the DM approach when the object size is not small (size>λ/20). The proposed technique utilizes piecewise sinusoidal basis functions to represent the currents on arbitrarily shaped wires with fine features, and modified RWG basis function for surfaces. The fields scattered by the object with fine features in MoM region are computed in the time domain on a planar interface. The time domain fields obtained at the planar interface are then combined with the FDTD update equations. In contrast to the existing techniques used to handle this type of problems, the proposed technique is both efficient as well as stable.

▼ The thesis is intended to be part of a larger process and field, by helping to increase understanding of how changed colour characteristics in urban green spaces can influence human experiences. More specifically, the thesis explores whether human colour perception is influenced by factors such as viewing distance, seasons, species mixture, or colourful artefacts incorporated in urban green spaces. In situ studies were performed in southern Sweden, using public parks and welldefined forest stands as experimental areas. Three empirical studies were conducted in the form of quasi-experiments and combined studies involving colour perception and environmental assessment methods. The main findings are structured around Johannes Itten’s colour contrast concepts from the 1960s (Itten, 2002), Berlyne’s arousal model (1971) and the concept of hedonic values. The main results are discussed in terms of the effect of viewing distances on colour perception and the effect of colour contrast on visitor experience. In addition, the findings are related to methodological considerations and constraints, with a discussion of a quantitative approach concerning determination of colours and the use of expert respondents. In today’s urban green spaces, bright and intense colourful artefacts are increasingly playing a role as visual contributors. According to the results, the coloured additions in green-dominated areas seem to affect human colour perception when viewed from both a short distance (3 metres) and a longer distance (15 metres) in a public park. These findings might also apply to colourful plantations in park environments like perennialand annual borders. The results also indicate that human experiences relate to perceived colour characteristics, which in turn relate to surrounding environmental colours and viewing distance. The findings emphasise that awareness of colour aspects, such as perceived colour contrasts and the effect of viewing distance on perceived colours and related human experiences, should be addressed in the planning and design of urban environment processes. The knowledge from this thesis could support landscape and garden designers in their work to develop outdoor environments that are attractive for humans.

Dissertação de Mestrado em Engenharia do Ambiente.

A publicação da Directiva-Quadro da Água, e a consequente necessidade de caracterização e classificação das massas de água, levou ao desenvolvimento de metodologias específicas para o efeito. No caso dos rios, foi desenvolvida a metodologia River Habitat Survey (RHS), no Reino Unido, entretanto testada em vários países europeus e em adopção ao nível nacional. No presente trabalho, foi testada a aplicabilidade da metodologia RHS nos cursos de água dos Açores, através da realização de transeptos em nove ribeiras da ilha de São Miguel. Nos transeptos realizados, foram observadas cerca de 81% das características previstas no formulário RHS. Outras observações pontuais contribuíram para aumentar em 11% a representatividade das observações em cursos de água regionais face ao previsto no formulário RHS, perfazendo assim 92% do mesmo. Entre os índices de qualidade aplicados na metodologia RHS, concluiu-se que o Human Modification Score se revelou eficaz na distinção dos cursos de água testados, enquanto o Habitat Quality Assessment não se afigura adequado como índice de qualidade ecológica. Conclui-se que o RHS é aplicável à rede hidrográfica dos Açores, embora mediante a inclusão de algumas características não previstas na versão 2003 do formulário RHS, que constam na proposta de adaptação à região agora formulada.

The publication of the Water Framework Directive and the consequent need to characterize and classify water bodies led to the development of specific methodologies for that purpose. In the United Kingdom, the River Habitat Survey (RHS) was developed to support the river classification. Thereafter, this methodology was tested in several European countries and is currently being adopted at national level. The applicability of the RHS in the Azores was tested, by conducting transects in nine rivers from the island of Sao Miguel. In those transects, about 81% of the features from the RHS form were observed. Using observations other than the transepts, there were identified another 11% of the RHS features, achieving 92% of the form for the regional rivers. Among the quality indexes applied to the RHS methodology, the Human Modification score was effective in distinguishing the watercourses tested, while the Habitat Quality Assessment is not appropriate as an index of ecological quality for the Azores. In general, it is concluded that the RHS is applicable to rivers in the Azores, although it was suggested the inclusion of some specific features absent in the 2003 version of the RHS form.

▼ The accuracy of the model used for prediction in Nonlinear Model Predictive Controller (NMPC) is one of the main factors affecting the closed loop performance. Since it is impossible to formulate a perfect model for a real process, there are always differences between the responses predicted by the model and the responses observed from the process. Hence, robustness to model error is an essential property that the controller must have to be adopted in industrial applications. Propagating the uncertainty in the model onto the variables used by the controller is one the key challenges for efficient implementation of a robust controller. Uncertainty propagation approaches such as Monte Carlo simulations and the Polynomial Chaos Expansions (PCE) has been found to suffer from exponentially increasing computational effort with the number of uncertain parameters. Accordingly, the main goal of this thesis is to develop a novel formulation of NMPC based on an uncertainty propagation approach that is more computationally efficient as compared to previously reported approaches. The proposed robust controller in this thesis is specifically targeted to biosystems that are modeled by Dynamic Metabolic Flux models. These models that are becoming increasingly popular for modelling bioprocesses are based on the premise that microorganisms have learned through natural evolution to optimally allocate their resources (nutrients) to maximize a biological objective such as growth or ATP production. Accordingly, these flux models are formulated by LP (Linear Programming) optimizations with constraints that are solved at each time interval and then can be used in conjunction with mass balances to predict the dynamic evolution of different metabolites. The uncertainty in these models is associated to inaccuracies of model parameters involved in the constraints. Thus, although the problem can be solved for particular model parameters by an LP, in the presence of uncertainty the problem becomes nonlinear since different active sets of constraints may become active for parameters’ values within their possible range of variation. Accordingly, the solution space of this nonlinear system can be divided into a set of polyhedrons where each point corresponds to a particular set of parameters within their range of uncertainty. The solution space is often referred in the thesis as the RHS (Right Hand Side) space since it is defined by the variations in the RHS of the constraints with respect to the uncertain parameters. To identify these polyhedrons a dividing procedure has been developed. Since all the polyhedrons can be proven to be convex cones based on a standard simplex form of LP, this dividing method is referred to as the Convex Cone Method (CCM). The regions found by the CCM method are then compared to regions calculated with 100 Percent Rule where the latter has been often used to find a region of existence of a particular tableau in the Simplex method. From this comparison it is found that the CCM can both identify all the possible tableaus…

▼ A chave para o sucesso de uma organização não está nas suas capacidades em gerir os bens tangíveis, mas antes em mobilizar e tirar partido dos seus bens intangíveis. Torna-se, assim, indispensável, numa sociedade que se caracteriza pela volatilidade da informação, na qual o ritmo de vida é cada vez mais acelerado e o conhecimento é um dos principais factores de competitividade, investir nas pessoas e no seu capital intelectual. Mas, para que isso se torne num valor acrescentado é preciso partilhá-lo através de REDES em ambientes cada vez mais colaborativos. Os ambientes virtuais de aprendizagem no formato e-learning poderão constituir-se como soluções bastante interessantes capazes de incentivar essa partilha e fixar e desenvolver o capital intelectual de uma organização. Nesta dissertação procura-se saber se existem condições organizacionais efectivas para a implementação de um modelo de blended learning utilizando uma plataforma de e-learning, que permita dar resposta às necessidades de formação contínua dos profissionais de saúde de um hospital privado. Para dar resposta a esta questão estuda-se o ambiente interno e externo no qual se insere. Numa primeira fase, analisa-se as condições de partida dando ênfase à percepção da gestão de topo no que se refere à tomada de decisão: mudar o modelo de formação actual para um formato inovador de blended learning. Numa segunda fase, consolida-se a análise anterior observando outros indicadores e desenha-se o modelo propriamente dito. É um estudo puramente exploratório, qualitativo, enquadrado num paradigma compreensivo - indutivo cujas evidências dão origem a um referencial de inovação na formação; ABSTRACT:The key to the success of an organization it’s not in their capabilities in managing tangible goods, but rather to mobilize and take advantage of its intangible assets. It is therefore essential in a society characterized by volatility of information, in which the pace of life is increasingly accelerated and knowledge is one of the main factors of competitiveness, to invest in people and in their intellectual capital. But for this to become an added value you must share it through networks in increasingly collaborative environments. Virtual learning environments in e-learning format may be very interesting solutions capable of empower this sharing, to establish and develop an organization intellectual capital. This thesis seeks to know whether there are actual organizational conditions for the implementation of a blended learning model using an e-learning platform, allowing the needs for continuing training of health professionals of a private hospital. To respond to this issue we study the internal and external environment in which it is inserted. Initially, we examine the starting conditions giving emphasis to the perception of top management in decision-making: changing the current training model for an innovative format of blended learning. A second phase consolidates previous analysis observing other indicators and draws the model itself. It is a purely… Advisors/Committee Members: Silva, Carlos Alberto da.

▼ Traditionally, joints are assumed to be either pinned or fully rigid, but in reality, many behave between these two extremes giving them a semi-rigid classification. By acknowledging the semi-rigidity of nominal pin joints, steel frames can be designed as semi-continuous in which the beam bending moments are partially transmitted to the column members and the need for lateral bracing is eliminated, thus reducing material and construction costs. This thesis presents the results of numerical and theoretical studies of the behaviour of bolted endplate connections to Rectangular Hollow Section (RHS) columns using flowdrill bolts and their applications in semi-continuous frame design. Such connections exhibit significant levels of initial stiffness, strength, and deformation capacity while being more cost-effective than fully welded connections. Despite this, there is limited theoretical work carried out that allows such connections to be designed using analytical methods. In addition, there are no standardised connection design tables like that for open section columns (SCI, 1995), thereby inhibiting their adoption in practice. In this thesis, newly derived equations for initial stiffness that have a greatly improved range of validity and accuracy over existing equations are presented. Equations for bending strength of a newly derived elliptical mechanism based on yield line theory and for membrane action based on internal work principles are given. Equations for flowdrill thread stripping due to gross deformation of the RHS face are also presented thus allowing prediction of all common RHS face failure mechanisms. Equations for deformation capacity are derived thus making it possible to predict the full load-deflection behaviour of the RHS face in tension component. When combined with existing equations for bolt and endplate components, it is possible to predict the full moment-rotation behaviour of bolted endplate connections to RHS columns. Extensive parametric studies using finite element analysis (FEA) as well as validation against existing tests show that the newly derived equations can accurately predict the component-level and whole joint behaviour for a wide range of configurations. Taking advantage of the initial stiffness properties that these connections offer, a parametric study is conducted to show that connections with relatively simple detailing can offer sufficient initial stiffness and strength to enable unbraced semi-continuous design of low-rise steel frames. A hand calculation method for SLS sway in semi-continuous frames is also presented thus allowing the designer to readily carry out scheme designs without advanced software knowledge. A systematic method for the detailing of these connections for use in unbraced frame design is presented to facilitate adoption in practice.

▼ The aim of this thesis is to assess the suitability of cold-formed rectangular hollow sections (RHS) for plastic design. The project involved an extensive range of tests on cold-formed Grade C350 and Grade C450 (DuraGal) RHS beams, joints and frames. A large number of finite element analyses was also carried out on models of RHS beams. The conclusion is that cold- formed RHS can be used in plastic design, but stricter element slenderness (b/t) limits and consideration of the connections, are required. Further research, particularly into the effect of axial compression on element slenderness limits, is required before changes to current design rules can be finalised. Bending tests were performed on cold-formed RHS to examine the web and flange slenderness required to maintain the plastic moment for a large enough rotation suitable for plastic design. The major conclusions of the beam tests were: (i) Some sections which are classified as Compact or Class 1 by current steel design specifications do not maintain plastic rotations considered sufficient for plastic design. (ii) The current design philosophy, in which flange and web slenderness limits are independent, is inappropriate. An interaction formula is required, and simple formulations are proposed for RHS. Connection tests were performed on various types of knee joints in RHS, suitable for the column - rafter connection in a portal frame. The connection types investigated were welded stiffened and unstiffened rigid knee connections, bolted plate knee joints, and welded and bolted internal sleeve knee joints, for use in RHS portal frames. The ability of the connections to act as plastic hinges in a portal frame was investigated. The most important finding of the joint tests was the unexpected fracture of the cold-formed welded connections under opening moment before significant plastic rotations occurred. The use of an internal sleeve moved the plastic hinge in the connection away from the connection centre- line thus eliminating the need for the weld between the RHS, or the RHS and the stiffening plate, to carry the majority of the load. The internal sleeve connections were capable of sustaining the plastic moment for large rotations considered suitable for plastic design. Tests on pinned-base portal frames were also performed. There were three separate tests, with two different ratios of vertical to horizontal point loads, simulating gravity and horizontal wind loads. Two grades of steel were used for comparison. The aims of the tests were to examine if a plastic collapse mechanism could form in a cold-formed RHS frame, and to investigate if plastic design was suitable for such frames. In each frame, two regions of highly concentrated curvature were observed before the onset of local buckling, which indicated the formation of plastic hinges and a plastic collapse mechanism. An advanced plastic zone structural analysis which accounted for second order effects, material non-linearity and…
