基于全过程非线性动力反应时程分析方法,对短程线型单层球面网壳结构在地震作用下的动力稳定性进行了系统研究,考虑了不同参数对其动力稳定性影响,其中包括:水平地震作用、竖向地震作用和三向地震作用的影响,材料非线性、矢跨比、初始几何缺陷、杆件截面、支座条件、结构阻尼和不同地震波等的影响,得出了一些有意义的结论,可为网壳工程设计提供参考。 Based on the whole-process nonlinear dynamic response time-history analysis method, the dynamic stability of the geodesic single-layer reticulated dome structure under earthquake action is studied systematically. The influence of different parameters on the dynamic stability is considered, Earthquakes, vertical earthquakes and three-way earthquakes, material nonlinearities, span-to-span ratios, initial geometric imperfections, bar cross sections, bearing conditions, structural damping, and different seismic waves. The conclusion can provide a reference for the design of reticulated shells.
