摘　　要：基于ANSYS建立了6个楼梯间有限元模型,通过模态分析与罕遇地震作用下的弹塑性动力时程分析,对比分析了各模型的结构动力特性、位移响应、加速度响应、应力分布及梯板采用分离式连接的竖向振动情况,以研究楼梯子结构采用不同连接方式及连接强度时对楼梯间结构抗震性能的影响。Based on ANSYS,6 staircase finite element models were established.Through modal analysis and elastoplastic dynamic time history analysis,the structural dynamic characteristics,displacement response,acceleration response,stress distribution of each model and the vertical vibration of stairs with separated connection are compared and analyzed.In this paper,the influence of different connection methods and connection strength on the seismic performance of staircase structure is studied.
