一种新型的混凝土结构双参数地震损伤模型
A New Earthquake Damage Model for RC Structure
【摘要】 在结构的抗震设计、未来震害预测、震后经济损失评估等过程中,一个重要的任务就是选择合理的反应量建立结构损伤评估模型,以定量计算出结构在地震过程中的损伤指标。在分析现有的损伤参数以及几种双参数地震破坏准则的基础上,结合损伤力学的基本原理,提出了一种新型的混凝土结构双参数地震损伤模型,并根据已有的实验结果确定了模型参数。
【Abstract】 During the process of seismic design of structures, prediction of earthquake damage in future and estimation of economic loss after earthquake, it is important task to select appropriate variables to establish damage models for offering quantitatively the damage indices of structures under earthquake. In this article a few types of damage variables and some two-parameter damage models are first analyzed, then a new damage model on the basis of damage mechanics is proposed and at last the value of the parameter in the model is given.
