摘　　要：在经典的结构理论研究的基础上,讨论了多自由度体系结构屈曲分析的数值方法,并给出了结构弹塑性、开裂和屈曲分析的一致理论,按宏观、微观和传递分析过程根据平衡稳定性判断准则构成了结构系统稳定性分析的完整框架,可用于工程结构的屈曲分析.Based on the study of classical structural theory,the numerical method of buckling analysis of multi-degree-of-freedom system structures is discussed,and the consistent theory of elastic-plastic,cracking and buckling analysis of structures is proposed.According to the macro,micro and transfer analysis processes,the complete framework of stability analysis of structural systems is formed on the basis of criteria of equilibrium stability,which can be used for buckling analysis of engineering structures.
