在对国内外钢筋混凝土梁的受剪性能进行较系统分析的基础上 ,补充了 1 1根钢筋混凝土简支短梁在顶部集中荷载和均布荷载作用下的试验 ,试验梁的主要变化参数为剪跨比、跨高比、水平腹筋率和垂直腹筋率 .根据试验结果 ,对试验梁的工作性能、主要的剪切破坏形态、混凝土项的抗剪作用、抗剪腹筋 (包括水平腹筋、垂直腹筋 )的作用等进行了较为深入的分析 ,提出了可适用钢筋混凝土深梁、短梁和浅梁相互协调的受剪承载力的统一计算方法 .
Based on a systematic analysis of the shear properties of reinforced concrete beams at home and abroad, the experiment is supplemented by 11 concentrated concrete short-slender beams under the action of concentrated loads at top and uniformly distributed loads. The main parameters of the experimental beams are Shear span ratio, span ratio, horizontal web ratio and vertical web ratio.According to the test results, the performance of the test beam, the main shear failure mode, the shear resistance of concrete, shear strength Abdominal tendons) were analyzed in depth, and a uniform calculation method for the shear capacity of the RC beams, short beams and shallow beams which are compatible with each other was proposed.
