Abstract

In view of the current situation that the numerical simulation parameter analysis of frame structure mainly focuses on the macro characteristics such as stiffness and displacement, the author uses ABAQUS finite element (FE)software to establish a three story two span steel reinforced concrete plane frame and carry out pseudo dynamic analysis. The reasonable constitutive relationship of concrete and steel, the constraint relationship between concrete and longitudinal reinforcement, stirrup and section steel, the reasonable seismic wave input mechanism and the structural damping of plane frame are fully considered in the modeling. By comparing the displacement and acceleration time history results in the finite element with the test results, the difference between them is small, which shows the rationality of the modeling method, and further analyzes the meso characteristics of plastic energy dissipation of the plane frame. The results show that the proportion of plastic energy dissipation of frame beam is greater than that of frame column; According to the material, beam and column reinforcement are the main energy consuming components of plane frame, followed by concrete, and the energy consumption of section steel is relatively small; The modeling method can efficiently and accurately simulate the pseudo dynamic performance of plane frame, and can be used as a reference for subsequent practical projects.
