以兰州某展览中心大跨度空间曲面管桁架结构屋盖为例，利用有限元分析软件ANSYS10．0建立结构有限元模型，并对结构进行多点多维激励下的地震反应分析，分别考察结构在一致地震动、仅考虑相干效应的空间地震动和同时考虑行波效应和相干波效应的空间地震动3种不同工况下的空间变化效应．

Abstrct:This paper takes large?span space tubular truss roof structure of an Lanzhou exhibition center as an ex?ample. By using ANSYS10.0, the structural finite element model was established and the structure response un?der multi?support and muli?dimensional seismic excitation analysis was conducted. The spatial effect was studied from three different modes which are consistent ground motions, spatially ground motion related with coherent effect and spatially ground motion related with traveling wave effect and coherent wave effects.
