砌体结构简支梁的梁端负弯矩初探

On primary exploration for negative moments of beam ends of simply supported beam of masonry structure

针对实际情况下砌体结构中钢筋混凝土梁的梁端不能自由转动这一现象,结合工程分析了该梁顶部纵向钢筋的合理配筋方法,得出了一些有益的结论,具有一定指导意义。

Aiming at the factual situation,the paper points out the phenomenon that the beam ends of the reinforced concrete beam can not turn around,analyzes the reasonable reinforcement method for the vertical reinforcement of the beam top part,and concludes some beneficial results,so as to have certain direction significance.
