钢筋混凝土深梁计算分析与设计研究

RESEARCH ON CALCULATION ANALYSIS AND DESIGN OF REINFORCED CONCRETE DEEP BEAM

文中主要探讨了深梁结构特点与一般浅梁结构特点的不同,研究分析了简支形式和连续形式的深梁,对深梁承载力公式进行了探讨,结论如下:深梁正截面上的应力分布规律不再服从平截面假定,且深梁跨高比数值越小,上述现象愈发显著;简支形式和连续形式的深梁二者破坏形式类似,较为不同的是,连续形式的深梁受弯截面出现纵筋屈服现象并不同于该截面屈服破坏。

This paper mainly discussed the difference between the structural characteristics of deep beam and general shallow beam,analyzed the simply supported and continuous deep beam,and discussed the bearing capacity formula of deep beam.The conclusions were described as follows.The stress distribution law on the normal section of deep beam was no longer obeys the plane section assumption,and the smaller the span height ratio of deep beam,the more obvious the phenomenon is.The failure forms of simply supported deep beams and continuous deep beams are similar,but the difference is that the yield of longitudinal reinforcement appears in the bending section of continuous deep beams,which is different from the yield failure of this section.
