［摘要］某总部塔楼总高度为400m，结构设计为满足使用空间的“无柱”要求，塔楼每层56根外框柱与外框环梁的连接节点均采用全偏心的节点连接形式，这是国内300m以上高层建筑中，首例大量采用偏心钢节点的工程项目。根据节点本身的特点，从节点构造的合理性、节点强度、节点刚度及对塔楼整体指标的影响等多方面进行考虑，运用有限元分析，进行深入研究，进一步验证此类节点在项目中的可行性。

Abstract:The total height of a headquarters tower is 400m. In order to meet the used space requirements of no columns, the connections between 56 frame columns and frame ring beams of each floor are all in the form of full eccentric. It is the first time to use such amount of  eccentric steel joints in a high\|rise building above 300m in China. Based on the characteristics of the joint itself, from the rationality of the structure, strength, stiffness, effects on the overall index of the tower and other aspects to consider, the depth analysis and research were done by using finite element analysis. And the feasibility of such joint in the project was further validated.

Keywords:eccentric steel joint; finite element analysis; construction design
