Finite Element Analysis of Dynamic Time History of Steel Frame Structure Filled with Rubber Brick

Abstract

Studying the influence of rubber brick infilled wall on the seismic performance of steel frame has theoretical and practical significance for the use of materials in civil engineering industry. The modal analysis of SF, RSF, LSF, R1SF and R2SF, and the nonlinear dynamic time history analysis under the action of two actual seismic waves and one artificial seismic wave are carried out by using the large finite element analysis software ABAQUS. Based on the comparison of the infilled wall materials and the layout of the infilled wall, the influence of the structural frequency and the maximum horizontal displacement is analysed. The structure of the study indicates that: under the action of seismic waves, the natural vibration frequency of the whole structure is reduced by adding the rubber brick infilled wall, and the increasing speed of the natural vibration frequency of the whole structure is slowed down. Under monotonic and low-cycle reciprocating loads, rubber brick filled walls can effectively improve the bearing capacity and lateral stiffness of the whole structure, improve the stress concentration of frame columns, but weaken the energy dissipation capacity of the whole structure.
