摘　　要：板锥网壳结构是一种受力性能合理,技术经济效益良好的新型空间结构形式。采用谐波法模拟了Daven-port脉动风谱;采用时程分析法对板锥网壳结构进行了风振响应时程分析,并对板锥网壳结构的风振响应特性进行了全面和深入的研究,为板锥网壳结构的抗风设计提供理论上的依据,得出了可应用于工程实践的重要结论。Plate-cone reticulated shell is a new type of space steel structures with good mechanical behavior and technical economy.In this paper,the wind-induced vibration response characteristics of plate-cone reticulated shell are studied.By using the wave superposition method,the fluctuation wind loads are simulated.By using the large general structural analysis software ANSYS,wind dynamic vibration time domain analysis of plate-cone reticulated shell are carried out.After comparing the wind dynamic vibration results of the model with different material,some important conclusions for plate-cone reticulated shell are obtained for practical design.
