北京CBD核心区Z6地块项目位于CBD核心区西南向,塔楼采用筒中筒结构,其中不规则网格外框筒由巨柱-巨撑-密撑组成,内筒由底部混凝土核心筒、上部钢框架核心筒组成。主要对外框筒中巨柱、巨撑、密撑相交形成的各类复杂节点进行分类,并通过设计原则、加强措施及有限元分析对节点进行设计,重点介绍了巨撑、密撑与巨柱连接节点、巨柱底部节点和巨撑下部与巨柱连接节点设计,旨在满足相应性能目标的同时使节点易于加工。
Beijing CBD core area Z6 plots project is located southwest of CBD core area, the tower adopts the cylinder tube structure, in which the irregular mesh outer cylinder tube consists of a huge column - giant strut - dense support, the inner cylinder from the bottom of the concrete core tube, the upper steel frame Core tube composition. It mainly classifies all kinds of complex nodes formed by the intersection of huge columns, giant bracing and dense bracing in the outer frame, and designs the nodes by design principles, strengthening measures and finite element analysis, and focuses on the connection between giant bracing, tight bracing and huge columns The nodes, the pylons ’bottom nodes and the pylons’ lower part are connected to the pylons to meet the performance goals and make the nodes easier to process.
