建筑结构地震损伤量化模型研究进展
|
摘要
指出建筑结构地震损伤模型是评价结构或构件在受到地震作用后破坏状态的无量纲指数,是震后对受损结构做出处理决策的重要理论依据,从构件和结构层次上系统地分析了几种典型的损伤模型,分析了这些模型的优缺点,在此基础上提出了地震损伤模型今后研究和发展方向的建议。
This paper pointed out that the building structure seismic damage model was the dimensionless index of damage state evaluated the structure or component after earthquake,was the important theory basis made decision to damaged structure after earthquake,systematically analyzed several typical damage models from the element and structure levels,analyzed the advantages and disadvantages of these models,on this basis proposed the future research and development direction for earthquake damage model.
