摘　　要：2021年实施的广东省标准《高层建筑混凝土结构技术规程》(DBJ/T 15-92—2021)(简称广东省高规)在抗震计算和性能化设计方面做了一些调整。根据广东省高规相关要求,通过YJK软件对某含错层的超限高层结构作设防地震验算和抗震性能化设计,采用Perform-3D进行动力弹塑性分析以验证按广东省高规设计的错层结构在大震中的性能。结果表明,对于该项目错层处框架柱,按照广东省高规进行的性能化设计,相较于《高层建筑混凝土结构技术规程》(JGJ 3—2010),纵向钢筋用量平均节省约7%。Guangdong province standard(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.
