The purpose of this study was to assess the correlation between flexural toughness and shear toughness of normalweight and lightweight fiber-reinforced concretes (FRC). A crimped steel fiber with a crescent geometry was used throughout. For flexure, third-point loading tests were preformed as per ASTM C1609. For shear, direct shear tests were performed using a modified version of the JSCE-G 553-1999 procedure. The flexural load-deflection curves were analyzed using the post-crack strengths (PCS^sub m^) method and the JSCE-G 552-1999 procedure. The shear load-deflection curves were analyzed using similar approaches. Results indicate that for a given fiber type and volume fraction, ...
