Abstract
This study presents alternative shear strength prediction equations for steel-reinforced concrete members without web reinforcements. It uses the techniques of dimensional analysis, interpolation function, and multiple regression analysis. More than 350 data were obtained from existing sources of reinforced concrete beam shear test results covering a wide range of beam properties and test methods. This analysis was done for both normal-strength concrete and high-strength concrete members with compressive strength up to 104 MPa (15,110 psi). The derivation of accurate cracking and ultimate shear strength prediction equations incorporated the original use of an interpolation function that takes into account the difference in behavior between the arch action of short beams and the beam action of long beams. The use of the interpolation function was instrumental in producing accurate cracking and ultimate shear strength equations as evidenced by the excellent correlation between experimental and theoretical v...
