摘　　要：邯郸客运中心主楼采用巨型钢-钢筋混凝土混合结构承担主要荷载。钢结构部分最大跨度达到40.5m,采用悬索-桁架体系,并由顶部桁架及大直径拉索将5~10层荷载传至混凝土核心筒。拉索作为主要受力构件,承受荷载较大,节点需进行专项分析。本文以拟建的邯郸客运中心主楼为研究对象,采用有限元软件ANSYS,建立三维实体模型对耳板式节点进行分析,结果表明,该节点受力性能良好,能较好地满足结构设计要求。Mega steel and concrete hybrid structure is used in the main building of Handan Passenger Transportation Center. The span of the steel structure part is 40.5meters, so the space suspension cable-truss is used to assume the main load. The sload of the story 5 to story 10 is transferred to the concrete tube by the truss on the top of the structure and the large diameter cables. As the main load-bearing members, it is necessary to analyze the joint of the large diameter cables. In this paper, the three-dimensional solid model was available to simulate the joint by the soft of ANSYS. The result showed that the mechanical character of the joint was preferable which could satisfy the need of the design.
