约束混凝土几种有代表性应力-应变模型及其比较

Introduction and Comparison of Several Representative Confinement Models for Concrete

材料模型是结构非线性计算机模拟分析的基础,而影响约束混凝土力学性能的因素众多,因此提出了相应的材料模型也很多。通过文献层面的分析比较,从众多约束混凝土模型中优选出其中六种加以介绍,并对各模型的应力-应变曲线进行了比较分析。

Lots of models for the confinement of concrete have been proposed because there are many variables playing roles in determining the behavior of confined concrete. After having compared the models from literature, several representative confinement models are introduced in this paper. At last, the stress-strain relationships of these models are compared.
