Abstract

During the 1999 Chi-Chi earthquake in Taiwan, various structures were damaged by fault displacement. To ensure the seismic safety of bridges, it is necessary to consider the effect of fault displacement in addition to inertia force. Most of the past researches investigated the effect of fault displacement using the static analysis, but it cannot capture the real behavior. Investigation using the dynamic analysis is therefore important. In this study, first, the method of imposing displacement wave was proposed which enables the dynamic analysis under fault displacement. Next, the validity of the proposed method was confirmed by a numerical simulation using a portal frame. Finally, the dynamic analysis of a cable-stayed bridge was conducted and the results were compared with those of the static analysis. It was found that the static analysis underestimates the sectional force and the necessity of the dynamic analysis was verified.
