Study on Seismic Performance of Lightweight Composite Wall Panels under Different Rebar Arrangement
In order to study the influence of different rebar arrangement methods on the seismic performance of prefabricated composite wall panels,this paper establishes three models of rebar arrangement to explore the structural seismic performance of composite wall panels.The finite element analysis software ABAQUS was used to simulate the forming of welded reinforced mesh wall panels,column-type reinforcement mesh wall panels and truss reinforcement mesh wall panels,and the failure patterns,load-displacement curves,bearing capacity,stiffness degradation,energy dissipation capacity and overall stability of the three models in the process of low-cycle reciprocating load were simulated and analyzed.The results show that the bearing capacity of the WB-2 cylindrical reinforcement cage is the largest,and it is 1.6 times of the maximum peak load of the welded reinforcement mesh of WB-1.In the seismic process,the stress of the composite wall panel expands from the corner direction of about 45°,and finally the stress concentration occurs.
