摘　　要：分析了多跨现浇混凝土双向板楼盖结构中楼面荷载的传递,计算了边区格中由荷载引起的边梁及边梁-柱节点的变形,这些变形包括边梁-柱节点的转动和边梁的相对扭转,而边梁-柱节点的转动是由板在两个正交方向传递的荷载所引起的。研究了变形对框架边梁扭矩的影响,推导出了框架边梁-柱结点转动变形和边梁自身相对扭转变形所引起的边梁刚性扭矩降低的计算公式,并结合常见的工程结构情况,进行了计算与分析,提出了框架边梁扭矩的简化计算方法。Transfer of gravity loads in reinforced cast-in-situ concrete frame structures with two-way floor slab was analysed, deformations of edge beams and joints in edge panels were calculated, these deformations included rotations in joints and relative torsions within edge beams, rotations in joints were generated form transferred loads in the orthogonal direction. Influence of these deformations on the torque of edge beam was researched, formulae to calculate the reduction of rigid torque by joint rotates of frames and torsional deformations within edge beam were presented, calculations on conventional structures were made,a concise torque calculation method of edge beam was given.
