Seismic Resistance Assessment of Multi-Span Continuous Bridge in Vietnam by Dynamic Response Analysis

摘要

The response of the bridge subjected to seismic excitation can be evaluated by dynamic responsernanalysis method. Vietnam is located at moderate seismic area; however, the seismic design has beenrnintroduced to secure the essential and important bridges. In this study, a typical concrete girderrnbridge in Vietnam (multiple frames in the longitudinal direction) is used to seismic resistancernevaluations. These evaluations are performed by performing nonlinear dynamic response analysisrnon FEA method. It is found that the stopper and the rubber gasket influence on response of thernbridge during Level 1 and Level 2 earthquakes.
