摘　　要：L形方钢管组合异形柱建筑效果好、抗震性能强,目前已应用于汶川等高烈度区的灾后重建。但是当下对L形方钢管组合异形柱抗震性能的研判多是基于其强轴的抗震性能,而对其弱轴的抗震性能研究较少。因此,通过对27个L形方钢管组合异形柱ABAQUS有限元模型的数值模拟,对其弱轴的抗震性能进行研究,得到其弱轴的破坏现象、极限层间位移角及延性系数的线性拟合公式。可为方钢管组合异形柱结构的推广及实际应用提供参考。L special-shaped column composed of concrete-filled square steel tubes has good architectural effect and seismic performance,and has been used in post-disaster reconstruction of high intensity areas such as Wenchuan.However,the current studies of the seismic performance of L special-shaped column composed of concrete-filled square steel tubes are mostly based on the seismic performance of its major axis direction,and the seismic performance of its minor axis direction is less studied.Therefore,through the numerical simulation of the finite element model of twenty-seven L special-shaped columns composed of concrete-filled square steel tubes based on ABAQUS,this study investigates the seismic performance of their minor axis direction.The failure phenomena,ultimate storey drift and linear fitting formula of ductility coefficient are obtained.The results of this study can provide reference for the popularization and practical application of special-shaped column composed of concrete-filled square steel tubes.
