摘要
静、动力稳定性问题是大跨空间结构分析中最重要同时也是最复杂的问题。本文首先对目前国内外在周期荷载、冲击荷载、阶跃荷载等各种动力荷载作用下结构和构件的动力稳定性研究现状进行简要回顾。然后 ,重点分析和介绍大跨空间结构在地震等任意动力荷载作用下的动力稳定性分析方法、关键问题和工程应用现状与前景。结合作者以往在这方面的研究成果 ,提出解决问题的思路和方法。
Static and dynamic stabilities are the most important and intricate problems in Large-span space structures. In this paper, the up-to-date advance on dynamic stability of all kinds of structures and members under periodic loading, impact loading, and step loading is reviewed. Then, it is focused on the introduction of the analysis methods, existing difficulties, engineering application of dynamic stability theory in large-span space structures under earthquake loading. Finally the strategy is suggested to slove these problems based on the achievements the author have gotten in the past.
