Response Sensitivity Of Highway Bridges To Random Multi-Component Earthquake Excitation, Kyle Cronin
Response Sensitivity Of Highway Bridges To Random Multi-Component Earthquake Excitation, Kyle Cronin
Electronic Theses and Dissertations
Highway bridges provide a critical lifeline during extreme seismic events and must maintain serviceability under a large range of earthquake intensities. Consequently, the advent of more computational power has allowed more advanced analysis approaches for predicting performance and vulnerability of highway bridges under these seismic loads. In traditional two-dimensional finite element analyses, it has been demonstrated that the incidence angle of the ground motion can play a significant role in structural response. As three-dimensional nonlinear time history analyses are used more frequently in practice, ground motions are still usually applied along a single bridge axis. It is unknown how three …
