Seismic performance-based design of an out-of-code high-rise building with staggered floors based on 2021 edition of Guangdong province specification of tall building
Guangdong province standard Technical specification for concrete structures of tall buildings(DBJ/T 15-92-2021)(referred to as Guangdong province specification of tall building)has made some adjustments in seismic calculation and performance-based design.According to the relevant requirements of the Guangdong province specification of tall building,the YJK software was used to carry out the fortification earthquake checking and seismic performance-based design of a super high-rise structure with staggered floors.Perform-3D was used for dynamic elastic-plastic analysis to verify the performance of the staggered floor structure designed according to the Guangdong province specification of tall building in the large earthquake.The results show that compared with Technical specification for concrete structures of tall buildings(JGJ 3-2010),the amount of longitudinal steel bars is saved by about 7%on average for the staggered frame columns of the project according to the performance-based design of the Guangdong province specification of tall building.
