Calculation and Analysis of Large-span Steel-concrete Composite Floor over a Swimming Pool

结合某泳池上方大跨钢-混凝土组合楼盖设计,采用通用建筑结构有限元软件STRAT对其精细建模计算,分析了梁板协同作用下的楼盖整体受力与变形,并与常规查表法、梁板中线对齐的有限元法结果做了对比,找出了三者的差异。在此基础上,对此类大跨钢-混凝土组合楼盖的设计提出了建议。

Combined with the design of a large-span steel-concrete composite floor over a swimming pool,the general finite element software STRAT is used to model and calculate its fine structure.The overall stress and deformation of the floor under the synergistic action of beam and slab are analyzed,and the results are compared with the results of the conventional table look-up method and the finite element method of beam and slab center line alignment,and the differences among the three are found out.On this basis,some suggestions are put forward for the design of this kind of long-span steel-concrete composite floor.
