摘要:
在系统分析钢筋混凝土梁受剪性能的基础上,进行了24根承受集中荷载和均布荷载的钢筋混凝土梁的受剪性能试验,主要考虑的因素有剪跨比(λ=a/h0)、跨高比(l0/h)、水平和垂直腹筋配筋率(ρsh和ρsv).详细阐述了梁的受剪特性、破坏形态、受压区混凝土的作用以及腹筋的作用(包括水平腹筋和垂直腹筋),并最终提出了钢筋混凝土梁斜截面受剪承载力统一计算方法.该方法可用于计算深梁、短梁及浅梁的斜截面承载力,计算结果与试验结果符合良好.
Abstract:
On the basis of the systematic analysis of the shear performance of reinforced concrete beams, the shear performance test of 24 reinforced concrete beams subjected to concentrated load and uniform distribution load was carried out, and the main factors considered were shear span ratio (λ=a/h0), span height ratio (l0/h), horizontal and vertical rib reinforcement ratio (ρsh and ρsv). Finally, a unified calculation method for the shear bearing capacity of reinforced concrete beams in oblique section is proposed. This method can be used to calculate the oblique section bearing capacity of deep beam, short beam and shallow beam, and the calculation results are in good agreement with the test results.
