摘　　要：为研究装配式T型钢空腹夹层板组合楼盖的受力性能,对其理论计算公式进行了推导,并利用ABAQUS有限元分析软件建立了四边简支承装配式T型钢空腹夹层板组合楼盖的有限元模型,探讨各影响因素对该组合楼盖抗弯承载力的影响程度。分析结果表明:钢板厚度和钢材强度等级的改变对组合楼盖抗弯承载力的影响十分明显,而上层浇筑混凝土板厚度的增加、混凝土强度等级的提高,及连接上层混凝土板与下部钢结构的栓钉间距的减小,对组合楼盖抗弯承载力有一定的影响。理论计算方法验证结果表明,将组合楼盖截面的整体弯矩按上、下肋构件截面的刚度进行分配,再分别按组合构件和拉弯构件进行设计计算的方法是可行的。In order to study the mechanical properties of assembled T-typed steel vierendeel sandwich composite floors,the theoretical calculation formula has thus been deduced,followed by the establishment of the finite element model of assembled T-typed steel vierendeel sandwich composite floors with four simple supports by using ABAQUS finite element analysis software,with a tentative inquiry into the change of each influencing factor on the flexural bearing capacity of the composite floors.The results show that a change of steel plate thickness and steel strength has a significant impact on the flexural capacity of composite floors,while the increase of thickness of upper pouring concrete slab,the increase of concrete strength and the decrease of stud spacing between the upper concrete slab and lower steel structure have a certain impact on the flexural capacity of composite floors.The results of theoretical calculation show that it is feasible to distribute the overall bending movement of the composite floor section according to the rigidity of the upper and lower rib sections,with a design and calculation of the composite members and tension bending members respectively.
