［摘要］平安金融中心为巨型结构体系，其带状桁架节点具有体量大、钢板厚、杆件多等特点，是典型的巨型框架结构节点。介绍该巨型结构体系带状桁架节点的设计原则。运用有限元软件ABAQUS对比分析两种巨柱内隔板形式，考虑混凝土与钢的共同作用，分析了节点在地震荷载作用下的受力性能。结果表明，水平向内隔板节点的性能优于垂直向内隔板节点的性能，水平向内隔板节点满足地震荷载作用下的受力性能要求。

Abstract: Ping′an IFC is a mega structure system. The belt truss joints have many features, including huge mass, thick steel plates, more steel members and so on. The design principles for the belt truss joints of the mega structure system were introduced. Two types of stiffening plates were analyzed and compared to find a more appropriate stiffening plate through using the general finite element software ABAQUS. Considering the combined action of concrete and steel, the mechanical performance of the joints was analyzed under seismic action. The result shows the performance of joints with the horizontal stiffening plate is better than that of the joints with vertical stiffening plate. Joints with horizontal stiffening plate can meet the performance requirement under seismic action.

Keywords: mega structure; belt truss; joint; stiffening plate; shear deformation
