| 摘 要： | 主要讨论了利用大型通用非线性有限元分析软件ABAQUS对钢筋混凝土构件进行非线性有限元分析,重点对ABAQUS提供的混凝土本构模型、破坏准则、钢筋的本构关系以及如何在ABAQUS中处理钢筋与混凝土的粘结滑移效应进行深入研究,并针对混凝土受拉区的非线性行为提出了固定弥散裂缝模型进行模拟。最后通过一个算例分析,将实验结果与数值模拟结果进行分析比较,证明了运用ABAQUS对钢筋混凝土构件进行分析有较好的精度。

| Abstract: | The commonly applied nonlinear finite element analysis software of ABAQUS is used to make nonlinear finite element analysis of reinforced concrete components;the emphasis of the analysis is put on the constitutive model and destructive standard of concrete,the constitutive relation of rebars and the bond slip between rebars and concrete;and Smeared Crack Model is proposed for the simulation of the nonlinear behavior at the tension area of concrete.And finally through a numerical example,the test result and ... |
