【Abstract】 To investigate seismic behavior of high-rise steel structures filled light walls,a serial of specimens of concrete filled steel tubular frame(CFST) with infill or external autoclaved aerated concrete(ALC) walls under low cyclic loading were conducted. The seismic behavior of the overall structures was evaluated according to hysteretic curves, failure modes and ductility. The analysis model was built by using ABAQUS software, to modify the beam-to-column connection, wall-to-beam connection and panel-to-panel connection etc. The accuracy of the analysis model was verified by the comparison of load-displacement curves and failure modes. The result shows that the seismic behavior of CFST frames with infill or external ALC walls behaves good seismic performance and deformation; the finite element analysis model can be used to analyze the collaborative stress and connection performance between CFST frames with ALC walls.更多还原
