摘　　要：建立了基于石膏模壳的混凝土空腹板架楼盖的有限元模型,通过施加竖向均布荷载对楼盖进行材料非线性分析,得出了其开裂荷载和极限荷载,描述了裂缝的形成、发展和破坏模式,总结了易开裂位置。通过修改模型几何参数,研究了参数的改变对现浇空心楼盖受力性能的影响,给出了荷载-挠度曲线图,对比了承载能力,得到较优楼盖模型,供设计人员参考。Based on gypsum mold shell finite element model of concrete empty web frame floor and the vertical uniformly distributed load by applying the material nonlinear analysis was carried out on the floor, it is concluded that the cracking load and ultimate load, and describes the formation and development of cracks and failure modes, and summarized the crack position. By modifying the model geometry parameters, studied the parameters affect the performance of the cast-in-place hollow floor stress, load deflection curve is given, and compared the carrying capacity, and get a better floor model, a reference for designers.
