摘要: 新开发银行总部大楼塔楼采用钢管混凝土柱框架⁃核心筒结构体系. 外框大柱采用钢管混凝土柱并沿平面 6 个角点均匀布置;外框大梁采用钢桁架,分别在 8、14、20、26 层设置形成环带桁架,与外框大柱共同组成了巨型外框;核心筒平面为六边形并在 6 个角部设置了钢骨. 塔楼以国内、外结构设计标准和银行、健康材料、室内环境等行业标准为设计依据,以建筑、结构高融合度为设计目标和理念,最终形成了巨型框架⁃核心筒结构体系. 通过采用结构抗震性能化设计手段,以及同时考虑防连续倒塌的关键节点有限元分析、大跨楼盖人行振动舒适度分析等专项分析方法,研究和验证了巨型框架受力特点下该结构体系在本项目中的适用性及合理性,实现了金砖银行塔楼的高设计标准、高融合度、优异结构性能的预定目标.

Abstract: New Development Bank Headquarters tower adopts concrete⁃filled steel tubular column frame⁃core tube structuresystem. The outer frame columns were made of concrete⁃filled steel tubular columns and were evenly arranged along the 6corners of the plane; the outer frame beams were made of steel trusses, which are set on the 8th, 14th, 20th, and 26thfloors to form ring⁃belt trusses , which together with the outer frame columns form a giant outer frame. The plane of the coretube is hexagonal and steel frames were arranged at 6 corners. The tower is designed based on domestic and foreignstructural design standards and industry standards such as bank, health materials and indoor environment, and takes thehigh integration of architecture and structure as the design goal and concept, forming a giant frame⁃core tube structuresystem. Through the use of structural seismic performance⁃based design methods, as well as special analysis methods suchas finite element analysis of key joints considering continuous collapse prevention design & seismic performance⁃baseddesign, and pedestrian vibration comfort analysis, it is studied and verified that the structural system under the stresscharacteristics of the giant frame is suitable for this structure. The applicability and rationality of the project have achievedthe predetermined goals of high design standards, high integration, and excellent structural performance for the BRICSBank tower.

Keywords:concrete⁃filled steel tubular column; ring belt truss; giant outer frame; seismic performance design; finiteelement analysis of joint
