| 摘 要： | 单层椭球面网壳结构体系跨度大,结构复杂,利用大型有限元结构分析程序对其进行了结构整体动力分析,得到了结构的自振周期和振型参与系数.该类型大跨度空间钢结构特点是:前几阶振型为整体水平振动,后面的振型为竖向振动和局部振动的耦合作用.由于各阶振型的相互耦合,在进行地震分析时,反应谱分析方法无法满足结构的精度要求,应考虑采用时程分析方法.

| Abstract: | The monolayer ellipsoidal reticulated shell system is large in span and complex in structure.Based on the large-scale finite element program for structural analysis,this paper carried out the structural integrity dynamic analysis on it,which resulled in the natural vibrating periods and modal participation coefficients of the structure.This type of long-span space steel structure was characterized by the lateral movement for the preceding vibration modes while the vertical and local vibration coupling effec... |
