Kingkey Dongbin Times tower in Shenzhen is a frame-corewall structure with a height of 194.35m.It is an out-of-code high-rise building with a height of over B-level.The four corners and the north and south sides were equipped with L-shaped walls or glyph walls and frame beams.In order to meet the functional requirements of the building,a large number of floor slabs and frame beams connecting the outer frame to corewall were cancelled on the second floor,forming skip-floor columns.The outer frame columns on the east and west sides of the 41st floor were retracted inward,and column transfer beams need to be set.The above difficulties increase the difficulty of structural design.Performance-based design was adopted to take corresponding strengthening measures for key parts,and special analysis was carried out for special parts,such as special walls such as L-shaped walls or one-shaped walls,skip-floor columns,and column transfer beams.The seismic performance of the whole structure was investigated by elastic-plastic dynamic time history analysis.The calculation results show that the seismic performance of the structure can meet the expected design goals.
