摘要
ABAQUS非线性分析能力突出,经常用于分析建筑结构在罕遇地震作用下的抗倒塌性能,而结构中的关键抗侧力构件——混凝土剪力墙一般采用软件自带的损伤塑性本构(CDP)进行模拟,但关于验证该模型模拟准确性的研究却很少。本文详细介绍了该模型在模拟混凝土剪力墙的滞回性能时各参数的设置方法,并模拟了7片墙体的循环加载性能,计算结果与相应的试验结果吻合较好。本文研究表明,作者提出的CDP模型的参数设置方法能够很好地模拟混凝土剪力墙构件在循环荷载下的滞回性能,可用于整体结构分析中。
ABAQUS is very powerful to solve nonlinear problems; therefore,it is often used to analysis the performance of the structure building under rare occurrence earthquake where the key member to resist seismic effect,i.e.concrete shear wall,is simulated by the built-in constitutive model named concrete damaged plasticity(CDP) model.However,research on the accuracy and reliability of this model has rarely been reported.In this paper,methods to determine the exact value of parameters in CDP model were discussed.Further,the cyclic performance of 7 pieces of concrete shear wall was simulated and it showed that the simulation results agreed well with those of the corresponding experiment.This paper proves that the methods approved by the author to set the values of the parameters in CDP model could reproduce the pinch effect of the concrete shear wall under cyclic loading,and it can be used to analysis the seismic performance of the whole building structure.
