摘　　要：本文对淄博体育中心体育场悬挑屋盖进行了比较精细的空间风振分析。在屋盖同步风洞试验的基础上,按空间随机风致振动方法考虑了屋盖多个振型的影响,计算并提供了4个风向下屋盖各结点的等效静力风荷载,同时分析了屋盖的最大动位移和杆件最大动内力,给出了位移和应力两种风振系数。本文的分析方法可供同类结构抗风设计参考。A Spatial Wind-induced Vibration Analysis was made for the cantilevered roof of Zibo Stadium in this paper. On the basis of simultaneous wind tunnel experiment, static equivalent wind loads on nodes of the roof in four directions were computed and provided according to the method of spatial random wind-induced vibration by the effects of multi-mode. The maximum dynamical displacement of the roof and the maximum dynamical internal force of the bar were given and wind-induced vibration coefficients of both displacements and stresses were also provided. The analysis method of the paper provided a reference to the similar project.
