摘    要:安定分析是结构设计或承载能力研究的一个重要方面。本文首先简单介绍了经典安定理论、分析方法及其工程应用,然后从影响安定性的诸因素出发,对安定理论的近期发展进行了综述,包括安定理论在热载荷、几何效应、应变强化效应、动力效应等方面的推广和应用,塑性应变(或残余变形)的限制方法,以及安定性的实验成果等。 

关 键 词:安定分析   塑性失效   结构设计   結构承载能力   热载荷

Abstract:Shakedown analysis is an important part of the structural design or the research on load-bearing capacity. In the present paper, the classical shakedown theory, the methods of shakedown analysis and their engineering applications arc first introduced briefly. Then, in terms of factors influencing structure, shakedown, the paper gives a survey on the recent development of shakedown theory, including its application in thermal load, geometric effects, strainharden-ing and dynamic effects, methods of bounding plastic strain and deformation, and experimental results and so on.
Keywords:shakedown analysis  plastic failure  structural design  load-bearing capacity of structure  thermal load
