This study evaluates the shear strength of steel fiber reinforced concrete (SFRC) beams from a database, which consists\r\nof extensive experimental results of 222 SFRC beams having no stirrups. In order to predict the analytical shear strength of the\r\nSFRC beams more precisely, the selected beams were sorted into six different groups based on their ultimate concrete strength\r\n(low strength with f 0\r\nc\\50 MPa and high strength with f 0\r\nc\\50 MPa), span-depth ratio (shallow beam with a/d C 2.5 and deep\r\nbeam with a/d\\2.5) and steel fiber shape (plain, crimped and hooked). Principal component and multiple regression analyses\r\nwere performed to determine the most feasible model in predicting the shear strength of SFRC beams. A variety of statistical\r\nanalyses were conducted, and compared with those of the existing equations in estimating the shear strength of SFRC beams. The\r\nresults showed that the recommended empirical equations were best suited to assess the shear strength of SFRC beams more\r\naccurately as compared to those obtained by the previously developed models.
