摘　　要：无上弦空腹桁架组合楼盖作为新型组合体系,由混凝土板、砣块(直腹杆)、栓钉抗剪连接件、钢制下弦杆组成。为了研究无上弦空腹桁架组合楼盖结构的受力性能,使用Ansys建立有限元模型并且介绍了建模方法与过程,对无上弦空腹桁架组合楼盖的仿真模拟有实际参考价值。As a new type of modular system,the chordless hollow web truss modular floor cover consists of concrete slab,weight block(straight web),spigot shear connectors,and steel bottom chord.In order to study the force performance of the topline-less open web truss composite floor cover structure,a finite element model is established by using Ansys and the modeling method and process are introduced,which is of practical reference value for the simulation of the topline-less hollow web truss composite floor cover.
