Response Analysis of Traveling Wave Effect on the Structure of Science Hall in West(Chongqing)Science City
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.
