摘　　要：广州东塔采用了带伸臂桁架的巨型框架-核心筒体系,其中巨型框架由8根巨柱和6道环桁架组成。从项目背景、结构体系及关键构件设计等方面介绍了基于性能化抗震(风)设计的原则;从结构概念出发,深入研究结构在地震(风)作用下的响应,并针对巨型柱、C80高强混凝土和内嵌双层钢板混凝土组合剪力墙等关键设计提出建议。Guangzhou East Tower adopted mega frame-core wall with outriggers as its main structure system.The external frame is comprised of 8 mega columns and 6 belt trusses.The principles for seismic and wind designs on the basis of performance were revealed in aspects of the project background,the structure system and the key element design.The structure performances under earthquake（wind） were analyzed based on the structural concepts.Valuable advices were provided for design of the key structure elements such as mega columns,C80 high strength concrete and concrete walls with embedded dual steel plates.
