摘　　要：文章采用时程分析法,考虑多维多点地震输入机制,研究索穹顶结构的地震性能,并着重分析预应力水平、矢跨比、斜索斜率对结构地震性能的影响,发现多维多点地震输入和行波效应对索穹顶结构地震响应有较大的影响,预应力水平、矢跨比、斜索斜率则对不同类型构件的地震响应影响程度不一,需要在设计时加以考虑。This paper uses the time history analysis method to study the seismic performance of the cable-dome structure by considering the multi-dimensional and multi-point seismic input mechanism.The influence of prestress level,risespan ratio and inclined cable slope on the seismic performance of the structure is emphatically analyzed.It is found that multi-dimensional and multi-point seismic input and the traveling wave effect have great influence on the seismic response of cable-dome structure.The influence of prestress level,rise-span ratio and inclined cable slope on the seismic response of different types of components is different,which needs to be considered in design.
