混凝土结构地震损伤的研究现状及发展趋向
|
摘要
一个恰当的、符合实际情况的地震损伤模型,一方面为结构抗震设计提供合理的破坏准则;另一方面则可为震后建筑物的安全性评估提供科学的理论依据。本文按照累积损伤模型和非累积损伤模型2类分类标准,从构件和结构层次上系统地分析和总结了几种典型的损伤模型。阐述了它们建立的依据,分析了它们的合理与不合理之处。基于此,对目前关于地震损伤研究的不足之处进行了总结,建议了其可能的发展趋向。
In order to provide the reasonable failure criteria for aseismic design and the scientific basis for the security assessment of the building suffered earthquake,the appropriate damage model according with factual situation should be established.At the two aspects of cumulative damage and non-cumulative damage model,this paper analyses and summarizes systematically several typical damage models in the levels of element and structure.It also discusses logical foundations of these damage models,and analyses their rationality or irrationality.Based on these discussions,the deficiency of studies on earthquake damage is summarized,and the possible work on this subject in the future is suggested.
