Beam and slab of RC floor system, which bear vertical load directly, act on each other and work together.
钢筋混凝土梁板体系中梁与楼板作为直接承担竖向荷载的构件，彼此之间相互作用，共同工作。
The formulation for element stiffness matrixs, and vectors of nodal of element with the upper beam element subjected to either vertical concentrated load or distributed loads is illustrated.
阐明了单元刚度矩阵以及在上层梁单元作用竖向集中荷载或分布荷载下单元节点荷载列阵的形成。
Due to the large span of the floor slab, the moment torsion of the beam, under the vertical load, is obvious.
由于板跨较大，竖向荷载使梁截面承受的扭矩较大。
The result of analysis show that there is more yield hinges on the top tow storey columns of 6-storey frame7. It means that the heavy vertical load go against to the beam hinges mechanism of frame.
分析结果表明，7度区六层框架上部两层柱子出铰随竖向荷载的增大而增多，竖向荷载的增大更不利于梁铰机制的形成。
