摘　　要：为研究钢管混凝土框架-ALC墙板结构的抗震性能,采用ABAQUS软件建立了结构的有限元模型并施加低周往复荷载进行分析,与已有试验结果比对,验证了建模和分析结果的有效性。在此基础上调整门洞尺寸及位置参数,分析参数对结构抗震性能的影响。研究结果表明,随着开洞率的增大,结构极限承载力减小,延性明显降低;当门洞位于墙板内部时延性随偏心率增加而减小,而墙板位于边缘时与其余试件均值极限荷载降低了11.2%,抗震性能最差。研究可为实际工程设计提供参考,并给出相关的设计建议。This paper studies the seismic performance of concrete-filled steel tubular frame-ALC wall panel structure through a finite element model of the structure established by using ABAQUS software under low-cycle reciprocating loads.The effectiveness of the modeling and analysis results is verified by comparison with the existing testing results.On this basis,the size and position parameters of the door are adjusted,and the influence of the parameters 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.
