The Study on 3D Seismic Pounding of the High-Pier Bridge Under Strong Earthquake
In this paper, the 3D nonlinear finite element model of a high-pier bridge is built based on OpenSees. It then analyzes the reaction rule under different ground motions and focuses on the differences of the effects of seismic pounding between uniform excitation and multi-excitation considering the effect of a traveling wave. The seismic responses of the high-pier bridge are closely related with its natural dynamic characteristics and the spectral characteristics of ground motion. The traveling wave effect amplifies the seismic pounding response, while the ends of piers are adversely affected, exacerbating the damage, and which has obvious influences to all bearings. Therefore, to consider traveling wave effect is necessary in the analysis of bridge seismic collision response.
