Mechanical performance analysis of prestressed socket assembled concrete frame structure relying on computer simulation analysis

Abstract

In order to improve the mechanical performance analysis of assembled concrete frame structure, this paper combines with computer simulation technology to analyze the mechanical performance of concrete frame structure, and uses the concrete damage plastic constitutive model provided by ABAQUS to define the nonlinear constitutive behavior of concrete. Based on the elastic-plastic model, the damage variables are added to the model, which can better reflect the performance of concrete under cyclic loading, such as stiffness degradation. In addition, this paper uses ABAQUS finite element analysis software to further analyze the structural parameters of this form of joints, and design related prestressed socket assembled concrete frame to study the seismic performance of prestressed socket assembled frame structure. Finally, the effectiveness of this model is verified by computer simulation.
