| 摘 要： | 针对民用高层建筑的多层钢-混凝土结构的抗震分析存在缩尺效应、环境限制等问题,本文基于纤维模型理论并采用PERFROM-3D软件建立有限元模型,给出大型混合结构的弹性动力时程分析和阻尼计算方程,并给出了一个17层的民用高层建筑算例。针对算例中的混合结构体,采用El-Centro地震动,输入不同的地震动模拟实际情况,探索不同地震工况对此类结构的影响,并给出该结构的抗震性能分析以及应对方法,具有较强的实践意义。

| Abstract: | In this paper, based on the fiber model theory and the finite element model established by PERFROM-3D software, we perform an elastic dynamic time-history analysis, provide a damping calculation equation for large hybrid structures, and present an example of a 17-story civil building.For the composite structure in the example, we used El Centro ground motion as input to simulate the actual situation and explore the influence of different earthquake conditions on this kind of structure.We also analyze the seismic performance of the structure and present related methods, which have strong practical significance. |
