抜粋

This paper presents the seismic behaviors of static pushover and dynamic response analyses of a half-through steel arch bridge subjected to earthquake waves and fault displacement. In static pushover analysis, the loading conditions were adjusted by controlling displacements at the end of stiffened girders and at the springings of arch ribs where the fault displacement was assumed to occur. In the dynamic response analyses, six seismic waves according to JSHB seismic waves were input and the seismic behaviors of the bridge model were discussed. Subsequently, both the 1999 Taiwan Ji-Ji Earthquake wave and the fault displacement wave obtained from the time integral of the acceleration response wave were applied and the response behaviors were investigated. The dynamic response analyses were carried out using earthquake waves including fault displacement in transverse, vertical and longitudinal (expanding and shrinking) directions in order to investigate seismic behaviors of the bridge model. According to the analytical results, it was found that the plastic members were clustered near the intersections of arch ribs and stiffened girders. The results of dynamic response analyses by the input of fault displacement show good agreement with those of the static analyses by displacement control method.
