对于现浇钢筋混凝土板肋梁楼盖结构,在进行双向板支承梁的荷载计算时,一般是近似地取板以45°角向四周传递,梁上的板传荷载也近似地取短跨跨长的1/2或1/3荷载分配给支承梁。板上究竟有多少荷载传到支承梁上、板边支承梁的荷载分配情况怎样?本文研究的内容有二:①从板的塑性极限的分 For the cast-in-situ reinforced concrete slab rib beam floor structure, when calculating the load of the two-way slab support beam, it is generally approximate to take the slab to the surrounding area with an angle of 45°, and the slab transfer load on the beam is also approximately the short span span. Long 1/2 or 1/3 loads are allocated to the support beam. How much load does the plate transfer to the support beam and the load distribution of the support beam on the plate? The contents of this paper are two: 1. The plastic limit of the plate
