论肋梁楼盖的整体弯曲

On Integrated Bending of Rib-Beam Floor Frame

阐述了砼肋梁楼盖在大柱网条件下 ,其计算中关于板支座无竖向位移的假定与实际工作情况有较大的出入。为了考虑板支座位移的影响 ,就要引入肋梁楼盖整体弯曲的概念 ,以考虑梁刚度对板受力的影响。

Discuss the reinforced-concrete rib-beam floor frame under the condition of big column network.In the calculation,the assumption of non-vertical displacement of slab support is quite different with the actual working condition.In order to consider the effects of slab support displacement,a concept of integrated bending of rib-beam floor frame is introduced,so as to evaluate the effects of beam rigidity under slab load,while reasonably explain the occurrence of oblique fissures in lattice slab of slab angle area during engineering construction.
