【摘要】 POA分析是一种结构非线性地震响应的简化方法。针对材料、构件和结构层次的损伤模型存在着脱节问题,本文提出基于两次POA分析的整体损伤模型,通过结构受损前后等效刚度的衰减来综合考虑结构刚度、强度和延性的退化,并通过算例验证该模型。更多还原

【Abstract】 The nonlinear static pushover analysis (POA) is a simplified computer method for seismic performance evaluation. In allusion to disjoint of damage model in material, member and structure level, two times POA-based global damage model is presented. This model includes synthetically stiffness, intensity and ductibility degrading by equivalent stiffness decay before and after damaged.更多还原
