Discussion on Response Spectrum Method and Time History Analysis for Long Span Reticulate Shell Structural Design/Sun Jianmei，Zhang Qilin(Department of Civil Engineering, Tongji University, Shanghai 200092, China)

Abstract:The response spectrum method indicates the ground seismic property and the structural response characteristic simply and clearly. The dynamics problem can be translated into the statics problem by the response spectrum method in the aseismatic analysis. But it will cause large errors for design of long span space and the complicated structures. The seismic responses are compared and analyzed by the response spectrum method and the time history method for the long span reticulate shells, in which the effects of the ratio vector and span are discussed. Some important conclusions are obtained through numerical examples, which can present the theoretical foundation for aseismatic design of long span space reticulate shells.

Keywords:response spectrum method；  time history analysis method； long span space reticulate shells; design analysis
