［摘要］在基于性能的抗震设计中，为了控制建筑结构不同程度的损伤，保证结构具有一定的可恢复性能，需要对建筑结构在不同性能等级下的层间位移角进行限制。利用PERFORM-3D软件对四个不同高宽比的高层钢管混凝土框架-型钢混凝土核心筒混合结构进行增量动力分析，得到了不同强度地震下连梁、墙肢、框架梁及框架柱损伤的大小和分布。根据各类构件在地震作用下的损伤分布，建议了高层钢管混凝土框架-型钢混凝土核心筒混合结构的性能等级划分方法。基于结构的易损性分析结果，得到了高层钢管混凝土框架-型钢混凝土核心筒混合结构在不同性能等级下的层间位移角限值，并研究了高宽比对不同性能等级下层间位移角限值的影响，为高层混合结构基于性能的抗震设计提供参考。

Abstract: In performance-based seismic design, in order to control different degrees of damage to the building structure and ensure the resilience capacity of the structures, it is necessary to limit the inter-story drift angles of building structures at different performance levels. Software PERFORM-3D was used to conduct the increamental dynamic analysis (IDA) analysis for four high-rise concrete-filled steel tube frame-steel reinforced concrete corewall structures with different height-to-width ratios, to obtain the damage size and distribution of connecting beam, wall limb, frame beam and frame column under different earthquake intensities. Based on the damage distribution of various components under earthquake actions, a method for classifying the performance levels of high-rise concrete-filled steel tube frame-steel reinforced concrete corewall structures was proposed. Based on the results of the vulnerability analysis of structures, the inter-story drift angle limists of the high-rise concrete-filled steel tube frame-steel reinforced concrete corewall with different performance levels were obtained, and the influence of height-to-width ratio on the inter-story drift angle limits for different performance levels was studied, providing a reference for performance-based seismic design of hybrid high-rise building structures.
