1. Sonavane, Trupti. Analysis of Arches.

Degree: MS, 2014, University of Colorado

URL: https://scholar.colorado.edu/cven_gradetds/119 

The purpose of this thesis is to develop a preliminary guide for the analysis and design of symmetrical circular arches. In the context of the graduate curriculum that typically limits itself to rectilinear structures, this thesis makes an effort to apply basic principles (virtual work and the flexibility method) towards deriving analytic solutions for different types of elastic arches (reactions and internal forces). To the best of our knowledge, this is the most comprehensive repository of such closed formed solutions. To illustrate their application, the preliminary design of a concrete arch is reported. Furthermore, analytical results are assessed to assist engineers gain a "feel" for arch behavior. The study broadly covers semicircular arches. The analysis includes different loading as well as support conditions that lead to statically determinate or indeterminate structural design cases. Effects of unsymmetrical loading conditions on these structures are also briefly covered in their analysis. The analytical solutions are derived with Mathematica, compared with reported analytical solutions (when available),validated with SAP 2000 models and used through Matlab for the design example. Further,this design guide helps relate structural behavior of semicircular arches with their geometry. Influence of aspects like span - to - rise ratio on horizontal thrust, support reactions, and forces across the span provides intuitive understanding of these structures. The study concludes with simplified analytical solutions and preliminary design recommendations. Advisors/Committee Members: Victor Saouma, Abie Liel, George Hearn.

2. Meshgin, Pania. Microstructure Characterization of Multi-Phase Composites and Utilization of Phase Change Materials and Recycled Rubbers in Cementitious Materials.

Degree: PhD, 2011, University of Colorado

URL: https://scholar.colorado.edu/cven_gradetds/214 

This research focuses on two important subjects: (1) Characterization of heterogeneous microstructure of multi-phase composites and the effect of microstructural features on effective properties of the material. (2) Utilizations of phase change materials and recycled rubber particles from waste tires to improve thermal properties of insulation materials used in building envelopes. Spatial pattern of multi-phase and multi-dimensional internal structures of most composite materials are highly random. Quantitative description of the spatial distribution should be developed based on proper statistical models, which characterize the morphological features. For a composite material with multi-phases, the volume fraction of the phases as well as the morphological parameters of the phases have very strong influences on the effective property of the composite. These morphological parameters depend on the microstructure of each phase. This study intends to include the effect of higher order morphological details of the microstructure in the composite models. The higher order statistics, called two-point correlation functions, characterize various behaviors of the composite at any two points in a stochastic field. Specifically, correlation functions of mosaic patterns are used in the study for characterizing transport properties of composite materials. One of the most effective methods to improve energy efficiency of buildings is to enhance thermal properties of insulation materials. The idea of using phase change materials and recycled rubber particles such as scrap tires in insulation materials for building envelopes has been studied.
