1. Chou, Raymond Neal. Review Of Load Rating And Posting Procedures And Requirements.

Degree: MSCE, Civil Engineering, 2013, Purdue University

All states are required to load rate and post bridges in order to comply with federal standards. Load ratings are performed in order to determine the safe live load capacity of a bridge, considering the existing conditions of the bridge. Based on the load ratings, the bridge is evaluated for load posting or strengthening. The Indiana Department of Transportation (INDOT) was notified that their practice for load rating and posting did not satisfy 23 CFR 650.313, which states that bridges shall be load rated and posted according to an American Association of State Highway and Transportation Officials (AASHTO) manual. The purpose of this study was to summarize and compare load rating and posting procedures used in other states and to provide recommendations and information necessary to modify the load rating and posting procedures in Part 3: Load Rating of INDOT's Bridge Inspection Manual (2010) in order to satisfy 23 CFR 650.313. In order to understand how load rating and posting is performed in other states, department of transportation (DOT) manuals were examined, questionnaires were sent to states, and additional states of interest were surveyed (State DOT Manuals and Personal Communication). AASHTO's The Manual for Bridge Evaluation, Second Edition (MBE, 2nd Edition) (2011), which is the current specification for load rating and posting bridges was reviewed, as well as older AASHTO bridge evaluation manuals (2008, 2003, and 1994). Based on this information, revisions were proposed to the INDOT Bridge Inspection Manual (2010) (Part 3: Load Rating) in order to eliminate current deficiencies. Advisors/Committee Members: Mark Bowman, Robert Connor, Michael Kreger.

2. Stroshine, Timothy Paul. Evaluating Different Bridge Management Strategies Using The Bridge Management Research System (bmrs).

Degree: MSCE, Civil Engineering, 2013, Purdue University

This project investigated the effects of varying two different elements of bridge management strategies. The first element was a trigger value (an NBI condition rating for a bridge component) at which a maintenance treatment can be performed. The second element was the budget. A new software program, the Bridge Management Research System (BMRS), was created to test these elements of bridge management strategies for Indiana's bridge network. BMRS is a simplified version of a previous bridge management software package developed by Purdue University, the Indiana Bridge Management System (IBMS). To test variations in the trigger values, three different bridge management strategies were proposed: a standard maintenance strategy, an early maintenance strategy, and a late maintenance strategy. The standard maintenance strategy allows for maintenance for bridge components with condition ratings from 1 to 5, the early maintenance strategy allows for maintenance for components with condition ratings from 1 to 6, and the late maintenance strategy allows for maintenance for components with condition ratings from 1 to 4. To test variations in the budget for Indiana's bridge network, three different budgets were used: a 150 million budget, a 200 million budget, and a 250 million budget. To evaluate each bridge management strategy, a distribution analysis, a threshold analysis, and a utility analysis were all performed. Distribution analysis looks at how many bridges are between two component condition ratings, threshold analysis looks at how many bridges have ratings greater than or equal to a given component condition rating, and utility analysis looks at how well each maintenance strategy meets certain criteria. After performing these analyses, this study found that, for any of the three budget levels, the standard maintenance strategy leads to better systemwide bridge performance than either the early or late maintenance strategies.

3. Reising, Rebecca. Risk-Based Bridge Inspection Practices.

Degree: MS, Civil Engineering, 2014, Purdue University

Improving bridge safety, reliability, and the allocation of bridge inspection resources are the goals of the proposed risk based bridge inspection practices. Currently, most bridges in the United States are inspected at a fixed calendar interval of 24 months, without regard to the condition of the bridge. Newer bridges with little or no damage are inspected with the same frequency as older, more deteriorated bridges thus creating inefficiency in the allocation of inspection resources. Because of limited resources, it is not possible to spend the necessary time examining bridges that are in poor condition and require extra attention since equal effort is also spent on bridges in good condition. In addition, no quantitative evidence exists to suggest that the 24 month inspection interval is the appropriate interval to achieve the desired level of safety. The proposed methodology incorporates reliability theory and expert elicitation from the Indiana Department of Transportation's Risk Assessment Panel, developed during this research, to rationally determine bridge inspection needs. Assessments are made based on the likelihood and consequence of failure for specific bridge components. The likelihood of failure is determined through attributes based on design, loading, and condition characteristics while the consequence of failure is based on expected structural capacity, public safety, and serviceability. By combining the expressions of likelihood and consequence for each component, an optimum inspection interval for the entire bridge can be determined through the use of risk matrices. The methodology was evaluated through case studies involving Indiana bridges. Over 30 years of historical inspection reports were utilized in the back casting process to evaluate deterioration levels and assess the adequacy of the risk criteria. Results of the case studies conducted during the research indicated that the risk analysis procedures provided suitable inspection intervals ranging from 24 to 72 months for Indiana bridges.
