摘　　要：以浙江科技学院学生活动中心钢屋盖为背景,研究复杂双层折板网壳的动力性能。对结构进行模态、稳定性和抗震性能分析。结果表明:该结构形式具有良好的受力性能、刚度和经济指标。在考虑双重非线性分析杆系结构时,应引入杆件失稳的本构关系。复杂折板网壳具有较好的抗震性能,但对地震波频率成分主要以低频为主时尤为敏感,因此需要足够的持时以保证计算结果的准确性。The dynamic performance of a complicated double-layer folded plate latticed shell was studied based on the steel roof project of Student Activity Center in Zhejiang University of Science and Technology. The structural modes,stability and seismic performance were analyzed. The results showed that the structural form had good mechanical property,stiffness and economic indicator. The constitutive relations of member buckling should be considered in the dual nonlinear analysis of member structure. The complicated double-layer folded plate latticed shells owned good seismic capacity,which was particularly sensitive to low frequency earthquake waves. Therefore,a long enough time for the seismic analysis was required to ensure the accuracy of the results.
