Numerical Simulation Analysis of Seismic Performance for Framework Structure Based on Rayleigh Damping Algorithm

Abstract

Seismic analysis of engineering structures can effectively ensure social and public safety, and in engineering practice. The elastic-plastic time history analysis of reinforced concrete frame structures is a more accurate analysis method for evaluating the seismic performance of the structure. According to relevant regulations, the seismic fortification intensity of a certain frame structure is 6 degrees. To analyze its seismic performance under earthquake action, this paper uses ABAQUS numerical simulation software combined with Ruili damping algorithm to establish a seismic model of the frame structure. The research results indicate that: (1) By calculating the interlayer displacement angle, the interlayer displacement angle of each layer meets the requirements of the specification, and the structure has good seismic performance. (2) The peak acceleration difference between the top layers of the structure decreases first and then increases from the bottom to the top. (3) There is a coupling relationship between structural deformation and the acceleration of the structure itself, and a coupling relationship between interlayer deformation and the peak stress at the top of the interlayer.
