摘要
从裂纹损伤结构的整体系统弹塑性分析出发，以一具有周向穿透裂纹损伤的圆柱壳门形刚架结构作为研究对象，利用理想化结构单元，分析了裂纹损伤直至裂纹扩展对结构的影响，探讨了理想化结构单元用于结构分析的适用范围及精度。
In this paper, the research is focused on elastic-plastic analysis of a portal frame structural system consisting of cylindrical shell with a circumferential through-crack damage. The influences of crack and its growth on structure are investigated by using the Idealised Structural Unitand, and the applicable range and accuracy of such idealized unit in pla8tical structure analysis are examined.
