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。
Taking the steel roof of student activity center of Zhejiang University of Science and Technology as the background, the dynamic performance of the complex double-decker reticle was studied. Structural modal, stability and seismic performance analysis. The results show that the structure has good mechanical properties, stiffness and economic indicators. When considering the dual nonlinear analysis of the rod system, the instability of the rod should be introduced into the constitutive relation. The complex folded plate shell has better seismic performance, but it is especially sensitive to the main frequency components of seismic waves mainly in the low frequency range. Therefore, enough timekeeping is needed to ensure the accuracy of the calculation results.
