几种有代表性的约束混凝土滞回模型

An introduction of several representative confinement hysteretic models

约束混凝土模型是结构非线性计算机模拟分析的基础之一,它包括应力—应变模型与滞回模型两个部分。通过文献层面的分析比较,从约束混凝土滞回模型中优选其中5种加以介绍,并对部分模型存在的不足进行了分析与修正。

The accuracy of nonlinear dynamic response analysis of computer simulation is partly decided by the accuracy of the material model. After having compared the literature, this paper introduces five representative confinement hysteretic models. At the same time, some errors in the models are analyzed .
