SIMPLIFIED EQUATION FOR ESTIMATING THE SHEAR CAPACITY OF REINFORCED CONCRETE BEAMS WITHOUT WEB REINFORCEMENT

A summary of a statistical study of shear capacity of non-prestressed reinforced concrete beams is presented. The study was aimed at obtaining a simplified equation by ignoring the effect of M/Vd on shear capacity of R.C beams. All beams used in this study had a shear span/effective depth of at least 2.5 and contained no shear reinforcement. The database used in the statistical analysis comprised 360 beams reported in the literature, including the results of twenty beams, which were cast and tested as a part of this study. An equation is proposed as a result of statistical regression analysis for shear strength of non-prestressed concrete beams without web reinforcement
