摘　　要：西部(重庆)科学城科学会堂主楼因南北地形高度原因,在其中部设置抗震缝,划分为南、北区两个结构单元,其东西向跨度为279 m,属于超长结构,使用大型结构分析软件SAP2000对结构进行多点激励计算,将其结果与一致激励的结果进行对比分析,研究行波效应在此项目中对结构整体与构件的影响。分析结果表明,考虑行波效应时的地震响应整体指标比一致激励计算值小。部分关键构件的行波效应影响因子超过1.0,应考虑行波效应对构件内力的不利影响,并根据对不同杆件的行波效应影响因子统计结果,选取其地震作用下的内力放大系数。结构的行波效应响应分析可以对结构构件的设计提供指导依据。Due to the height of the north and south terrain,the main building of the Science Hall in the West(Chongqing)Science City is divided into two structural units,the south and the north,with an east-west span of 279 m,which belongs to the ultra-long structure.SAP2000,a large-scale structural analysis software,is used to perform multi-point excitation calculation on the structure.The results are compared with the results of uniform excitation,and the influence of traveling wave effect on the whole structure and components is studied in this project.The results show that the overall seismic response index considering the traveling wave effect is smaller than that calculated by the uniform excitation.When the influence factor of traveling wave effect of some key members exceeds 1.0,the adverse influence of traveling wave effect on internal force of the structure should be considered,and the internal force amplification coef‐ficient under seismic action should be selected according to the statistical results of the influence factor of traveling wave effect on different members.The traveling wave utility response analysis of structures can provide guidance for the design of structural components.
