摘　　要：以某体育馆网架为研究对象,建立其参数化模型,利用有限元分析软件ANSYS对其进行整体结构静力分析、自由振动模态分析和随机振动分析,得到该网架的振动模态频率和振型,确定网架在地震波作用下关键节点的PSD响应,所得结果可对验证原设计和指导设计修改提供理论依据。With the lattice truss of gymnasium as the research object, a parametric model of grid frame is established. The static, natural modal and random vibration analyses are carried out by ANSYS, the natural frequencies and modes of vibrations of the lattice truss are worked out. And the PSD response of keypoint under the seismic wave is confirmed. The results can provide academic basis for the improvement of design.
