摘要
超高层总部塔楼建筑总高度为400m,采用密柱框架-核心筒结构体系,不设结构加强层,与传统的超高层框架-核心筒结构二道防线抗震设计不同,对本工程采用内外结构整体共同协调作用的抗震理念进行体系论证和设计,并针对结构设计中抗震设计的主要关键部分,如剪力墙的拉剪设计、梁柱偏心节点、核心筒斜墙收进等进行了深入的设计研究,从而确保整体结构设计的安全可靠和经济合理。
As a 400 meter high building, the structural system of this headquarter building is close column frame and corewall system without strengthened stories. Different from dual-defenses seismic design of traditional super-tall frame and corewall system, this structural system induced seismic concept of integrated work for external and internal structures to analyzeand design. Key parts in seismic design were deeply studied, such as tension and shear design of shear wall, beam-columneccentric connection and setback of inclined shear walls, which ensured the safety and economy of the building.
