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.
