Calibration and Application of Concrete Stochastic Damage Model
摘要
Abstract
The stochastic damage model for concrete is introduced in the paper.The fundamental parameters of the model are calibrated through the concrete constitutive model in the Chinese design code.In order to make the model convenient for engineering applications,some modifications are made to account for the complicated interaction effects between reinforcement steels and concrete in realistic structures.Then the model is implemented into the structural analysis software ABAQUS and OpenSees through user subroutines,and used to simulate different kinds of structural member experiments.The results indicate that the proposed model can reflect the mechanical behaviors of concrete and reinforced concrete members and structures,and it offers an effective way for nonlinear analysis of structures in engineering.关键词
