Experimental study on shear strength of high-strength concrete beams

Abstract

The authors conducted a comprehensive experimental and analytical investigation to assess the concrete component of shear resistance Vc in beams made with high-strength concrete. The experimental program consisted of testing 24 beams (18 with stirrups and six without stirrups) to determine the contribution to shear resistance by the concrete component. Test data from six other investigations covering 125 specimens are also analyzed. The data from the experiments and literature are compared with the shear provisions of high-strength concrete from selected codes. When extrapolating current code provisions to determine the concrete component of shear resistance for high-strength concrete, the a..
