摘　　要：在传统的钢筋混凝土楼盖设计中,梁、板内力计算是独立的,不考虑梁板之间的相互作用。以梁板结构框架梁为研究对象,采用SAP2000对不同梁板刚度比的梁板结构进行整体建模分析,并与传统计算分析方法进行比较,探讨了两种分析方法对框架梁内力计算结果差异性原因。为竖向荷载作用下梁板结构框架梁内力分析提出了一种考虑梁板相互作用的简化方法,并给出了框架梁内力简便计算公式。In traditional design method of reinforced concrete beam and slab structures,the internal force of beam and slab are calculated respectively and the interaction between beam and slab is ignored.In the paper,models with different stiffness ratio of beam and slab are built and analyzed by program SAP2000,and the reasons for the different calculation results of the beam internal force by the two analysis methods are explored.The simplified analysis method considering the interaction between beam and slab is put forward for calculating the beam internal force of the structure under the vertical load,and the simple calculation formulae are presented.
