Truss Bridge Damage Localization And Severity Estimation Using Influence Lines, Hamoud Alshallaqi
Truss Bridge Damage Localization And Severity Estimation Using Influence Lines, Hamoud Alshallaqi
Civil and Environmental Engineering Theses and Dissertations
The safety of bridges is one of the primary concerns of researchers, engineers, and bridge owners and managers, especially when bridges are approaching the end of their intended service lives. The estimation of bridge condition and remaining service life is critical to prioritize the allocation of available funding for repairs and rehabilitation. Various methods, including both dynamic and static approaches, have been developed to detect and localize bridge damage and estimate its severity. This research presents a methodology for detecting a single damaged member in a truss bridge and estimating the severity of the damage using static vertical deflection influence …

Infrastructure Deficiency Correlation With Pedestrian/Cyclist Crashes: A Data-Driven Approach, Farbod Tavakkoli Khomeini, Barbara Minsker, Michael Hahler, Janille Smith-Colin, Xinlei Wang
Civil and Environmental Engineering Theses and Dissertations
A model for identifying the impacts of infrastructure deficiency on road traffic safety is needed to help governments prioritize strategic investments to increase public safety. During the 2010-2019 period, U.S. pedestrian and cyclist fatalities rose by 44% and 36%, respectively, and previous studies have shown a positive correlation between pedestrian/cyclist crashes and low-income areas. To our knowledge, this study is the first to investigate further the reasons behind the higher probability of pedestrian and cyclist crashes in low-income areas. The proposed hypothesis is that the higher probability of pedestrian and cyclist crashes in low-income areas correlates with higher infrastructure deficiencies …
