摘要:
基于大跨径桥梁地震反应分析方法,建立了斜拉桥动力分析空间有限元模型.考虑了几何非线性对结构动力特性及地震响应的影响,以一座大跨径预应力混凝土斜拉桥为研究对象,采用直接积分法对该桥进行了地震非线性时程分析.根据该桥的方案设计,比较了两种塔梁连接方式下结构的动力特性,分析了桩土作用效应对结构地震响应的影响.计算结果表明:在大跨径斜拉桥抗震设计时,应考虑桩土相互作用的影响;人工拟合地震动和相近场地实测地震动记录的计算结果相差较大,在抗震复核中应取最不利荷载作用.
Abstract:
Based on the seismic response analysis method of long-span bridges, a spatial finite element model of dynamic analysis of cable-stayed bridges is established. Considering the influence of geometric nonlinearity on the dynamic characteristics and seismic response of the structure, a long-span prestressed concrete cable-stayed bridge was used as the research object, and the seismic nonlinear time history analysis of the bridge was carried out by direct integral method. According to the scheme design of the bridge, the dynamic characteristics of the structure under the connection mode of the two tower girder are compared, and the influence of pile soil effect on the seismic response of the structure is analyzed. The calculation results show that the influence of pile-soil interaction should be considered in the seismic design of long-span cable-stayed bridge. The calculation results of the artificial fitting ground motion and the measured ground motion records of similar sites are quite different, and the most unfavorable load should be taken in the seismic review.
