摘　　要：建立了一套在空间框架中考虑楼板刚度的有限元计算模型,使用该模型分析比较了平面框架、不考虑楼板的空间框架和考虑楼板作用的空间框架三种情况下梁、柱内力的差别,从而论证楼板及框架的空间效应。将有限元模型计算所得的楼板内力分布与常规设计计算方法所得结果进行比较,得出考虑空间框架与楼板联合作用后对楼板设计的影响。A FEM model in which plate stiffness in taken into account in the spatial frame is established. The following three models,plane frame,spatial frame without plates and spatial frame with plates are considered.The differences in the distribution of intrnal forcs in bcams and bars of the three modls vrify the frame spatial effect and plate effect.The internal forc of the model is compared with that of traditional design method,it comes to the conclusion that combination effect of spatial frame and plate should be taken into account in the design of spatial frame with plate.
