RESEARCH ON THE SEISMIC PERFORMANCE OF CONCRETE-FILLED STEEL TUBE FRAME-ALC WALLBOARD STRUCTURES
This paper studies the seismic performance of concrete-filled steel tubular frame-ALC wall panel struc-ture through a finite element model of the structure established by using ABAQUS software under low-cycle recipro-cating loads.The effectiveness of the modeling and analysis results is verified by comparison with the existing test-ing results.On this basis,the size and position parameters of the door are adjusted,and the influence of the parame-ters on the seismic performance of the structure is analyzed.The results show that the ultimate bearing capacity of the structure decreases and the ductility obviously decreases with the increase of the opening rate.When the door is located inside the wall panel,the ductility decreases with the increase of eccentricity,whereas the mean limit load of other specimens decreases by 11.2%,and the seismic performance is the worst when the wall panel is located at the edge.The research may provide the design reference for practical engineering and give relevant design suggestions.
