混凝土本构模型的选用对RC柱非线性分析的影响

Impact on Nonlinear Analysis of RC Columns under Different Concrete's Constitutive Models

混凝土本构关系是混凝土结构研究的基础。分析不同的混凝土本构模型对RC柱非线性分析的影响,通过选用不同的本构模型对RC柱所得理论分析结果与相应试验值的比较,表明选用不同的混凝土本构模型对RC柱非线性分析有显著的影响。

The concrete＇s constitutive relationship is the basis for the study of concrete structure. The responses of RC columns under different concrete constitutive models are analyzed here. Based on the comparison between the theoretical analysis results of RC columns with different concrete constitutive models and the test results, the conclusion is obtained that the choose of different concrete＇ s constitutive model has the significant impact on the nonlinear analysis of RC columns.
