为什么板负筋要保证在正确位置上呢?原因是板面荷载由板传递给梁,梁边缘的板受到负弯矩和剪力等荷载效应的影响,是受力较复杂的部位,为防止板与梁相连处产生裂缝,应在板面沿梁方向配置垂直于梁的负筋。负筋外面的混凝土因受到负弯矩等作用力的 Why negative plate to ensure that the board in the right place? The reason is that the plate load transfer from the plate to the beam, the beam edge of the board by the negative bending moment and shear load effects, is the force of more complex parts, to prevent Cracks are generated at the connection between the plate and the beam, and the negative bars perpendicular to the beam should be arranged along the beam direction of the plate. The concrete outside the negative reinforcement is affected by negative moments and other forces
