钢筋混凝土受弯构件受剪承载力统一计算
The Unified Calculation Method for Shear Capacity of Reinforced Concrete Flexural Members
摘要
Abstract
Based on the systematic analysis of the shear behavior for reinforced concrete beams, the paper presents an experimental investigation involving 24 reinforced concrete beams subjected to concentrated and uniformly distributed loads. Four main factors are considered, namely shear-span ratio (λ=a/h0) , span-depth ratio (l0/h), horizontal and vertical web reinforcement ratio (ρsh & ρsv). According to the test results, the working behavior, shear failure modes, the action of concrete compression zone as well as shear (web) reinforcement (including of horizontal and vertical web reinforcement) are further elaborated. Furthermore, the unified calculation method for shear capacity of beams is presented, which can be used to calculate the shear capacity of deep beams, short beams and even normal beams. The proposed formulas' calculation results are in good agreement with the test results.关键词
