摘要
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。
According to the full-range nonlinear dynamic response analysis method, dynamic stability of geodesic single layer reticulated shells under earthquake excitation is discussed systematically. Primary parameters are taken into account, such as combinations of vertical and horizontal earthquake action, material nonlinearities, rise to span ratios, initial geometric imperfection, cross-sectional areas of members, supporting condition, structure damp and different earthquake waves and so on. The results obtained in this paper can provide a valuable reference for practical design of reticulated shells.
