摘　　要：建立了柱支承筒芯内模现浇钢筋混凝土空心楼盖和对比实心楼盖的有限元模型,确定了单元类型和网格划分方案,分别对柱支承筒芯内模现浇钢筋混凝土空心楼盖和对比实心楼盖运用ANSYS软件进行了有限元分析,验证了有限元分析计算结果的正确性,并将柱支承筒芯内模现浇钢筋混凝土空心楼盖结果(应力、挠度)与对比实心楼盖相应结果进行比较,分析了柱支承筒芯内模现浇混凝土空心楼盖的变形特征,内力分布规律,可供设计人员参考.This paper sets up the finite element model of the column - supported tube filler cast - in - situ hollow floor and the corresponding solid floor, and determines the element type and mesh partition scheme. Both the hollow floor and the corresponding solid floor are analyzed by using finite element method in ANSYS software. Then the correctness of the finite element results is verified. The results （the stress, deflection） of the hollow floor and those of the corresponding solid floor are compared with each other accordingly. The deformation characteristic of the column - supported cast - in - situ hollow floor with tube fillers is analyzed, and so is the internal mechanics distribution law of the hollow floor.
