摘要
本文袭用静力稳定分析中的“一致缺陷模态法”,并将李雅普诺夫运动稳定理论引入结构分析,通过两个典型算例,检查了单层网壳结构在简谐荷载、阶跃荷载及三角形脉冲荷载作用下,初始缺陷对其动力稳定性能的影响.
Based on the method for imperfection analysis just as used in the analysis of static stability, the effect of initial imperfection on the large displacement stability behavior of two well-known types of single layer reticulated domes subjected to dynamic loads is examined in this paper. Three types of time-dependent loading cases are considered in the analyses,namely,step load of infinite duration sinusoidal load of infinite duration and triangular impulsive load.
