摘　　要：空间网壳跨度大、空间造型多样,往往属动力敏感性结构.本文通过黄山体育馆屋盖网壳的静动力分析,分析了该类型网壳的受力特点.在地震作用分析中采用了地震反应谱方法,并与静力作用进行了比较.在风振响应分析中,考虑了前12阶振型,分析了各阶振型对脉动风力的贡献,并分析了脉动风力相对静风力的影响比例,对各风向的作用进行了分析.本工程位于低烈度区,相对地震作用而言,风作用更为显著.本文为将来类似工程提供了一些可借鉴的资料.The spatial reticulated shells are dynamic-sensitive structures because of large span and spatial multiformity. This paper presents static and dynamic analysis on the roof reticulated shells of HuangShan gymnasium, and analyses the mechanical characteristics of this model of reticulated shells. The mode decomposition response-spectrum method is used in the seismic analysis, and the seismic response is compared to static action. The first twelve modes and every wind direction are included in the wind induced vibration response analysis, and contribution of every mode shape to the response is obtained. It is shown that wind action is more prominence than earthquake action based on the low seismic fortification intensity of Huangshan city.
