摘　　要：按照《建筑抗震设计规范》(GB50011-2010)的要求,计算不考虑楼板内钢筋与考虑楼板钢筋的梁端受弯承载力,证明现浇楼板内钢筋对梁的承载力具有增大作用,通过采用楼板开角缝的方法,计算分析梁端受弯承载力的变化情况。计算结果表明,采取开角缝的措施之后,梁端受弯承载力降低17%,削弱了板内配筋对梁端受弯承载力的影响。According to ＂Code for seismic design of buildings＂ （GB50011-2010）, the flexural capacity of beams of steel reinforcement in floor should be taken into account instead of steel reinforcement. It is prove that the flexural capacity of beams can be enhanced by cast-in-place steel reinforcement in floor. Through using the approach of slot- ring in floor to calculate and analyze the change of the bending resistance of the beams. The results show that the flexural capacity of the beams＇ end decreased 17% after taking the measure of slot-cutting in cast-in-place floor, and weakened the effect of flexural capacity of steel reinforcement in floor on beams.
