摘　　要：介绍某大空间宴会厅钢桁架组合楼盖的结构选型、结构分析、设计过程及关键受力部位典型节点的非线性有限元分析。与普通组合楼盖相比,采用钢桁架组合楼盖能更有效地发挥混凝土的抗压和钢材的抗拉性能,并能够更好地提高结构的刚度和承载力,减少用钢量,取得较好的经济效果。The structural analysis and design of steel truss composite floor used in a banqueting hall are introduced.The nonlinear finite analysis on the key part,the typical joints is also carried out.Compared with traditional composite floor,truss composite floor has some advantages including greater rigidity and bearing capacity,lower quantity of steel and fabrication cost.In addition,truss composite floor makes better use of the mechanical property of concrete and steel.

关 键 词：钢桁架 组合楼盖 典型节点
