摘要:
介绍了实现非一致地震动作用采用的等效人工边界单元和等效荷载法，采用自由场模型验证输入的正确性．以某在建地铁车站为背景，建立了三维地铁车站模型，计算了不同频谱地震波在一致与非一致波动入射工况下地铁车站的地震动反应，分析了该地铁车站在非一致地震动作用下的反应特性．总结了非一致地震动作用对车站结构反应的影响，分析了不利位置地震动内力反应，得出长跨度地铁车站有必要考虑地震动非一致因素影响作用的结论并提出抗震建议．
Abstract:
An artificial boundary element and equivalent loading method are introduced for considering the non-uniform seismic ground motion. Free field finite element is built to verify the correctness of the input. Taking a subway station under construction in the background, the 3D finite element model of the subway station was established, the different seismic wave spectrum under the working condition of uniform and non-uniform wave incident seismic ground motion response of a subway station was calculated, and the subway station under the effect of non-uniform seismic response characteristics was analyzed. The responses of subway station under spatially non-uniform ground motion are summarized and internal forces of weak positions studied. It concludes that the non-uniform factor needs to be considered for the long span subway stations. An advice of anti-seismic is come up with
