HDR隔震支座梁桥横向碰撞参数的研究
Study on Lateral Pounding Parameters of HDR Isolation Bearing Bridge
摘要
Abstract
In recent years,the bridge earthquake damage investigation shows that girders and seismic retainers of small and medium-span bridges suffer severe damage because of pounding between girders and seismic retainers under lateral earthquake excitation.In order to realize the application of using isolation bearing to reduce the lateral pounding of medium and small-span bridges,by using HDR high-damping isolation bearing,a lateral pounding model considering the bearing nonlinearity,pier-column elastic-plastic behavior and pile-soil interaction was established.The effect of HDR bearing stiffness,contact element stiffness,initial clearance and other parameters on the lateral impact of isolated bridge is studied in detail by nonlinear seismic response time-history analysis method.The results show that the lateral pounding response of the bridge can be effectively reduced by adopting the large stiffness of the HDR bearing and reasonable stopper rigidity.关键词
