在间接加载情况下,钢筋混凝土悬臂梁支座斜截面抗剪强度有所降低。降低幅度不如间接加载简支梁大,并有不同于简支梁剪切破坏的特点。本文通过实验及理论分析,探讨了间接加载钢筋混凝土悬臂梁抗剪强度变化的机理,找出了有关影响因素,从而提出了有关的补强建议。文中针对间接加载时悬臂梁的特点,强调了补强中的构造问题。 In the case of indirect loading, the shear strength of the oblique section of the reinforced concrete cantilever beam support is reduced. The magnitude of reduction is not as great as that of indirect loading of simply supported beams, and it is different from the shear failure of simply supported beams. In this paper, through experiments and theoretical analysis, the mechanism of the shear strength change of indirectly loaded reinforced concrete cantilever beam is discussed, relevant influencing factors are found out, and relevant reinforcement suggestions are put forward. For the characteristics of the cantilever during indirect loading, the construction problem in the reinforcement is emphasized.
