Previous research indicates that conventional stirrups can be eliminated by adding a sufficient amount of steel fiber in the concrete. Because shear reinforcement is hard to design in the member with narrow or irregular section, use steel fiber as shear reinforcement may break many geometric constraints on concrete design. In order to make fiber reinforced concrete (FRC) for more general use, the current need is to quantify the effectiveness of steel fiber. The purpose of this investigation is to evaluate the shear strength of FRC. Since there are already many researchers proposed their own equations for predict the shear strength of FRC, this study analyzed each equations and compared the accuracy. In addition, this study also collected many shear test data, constructed the database to derive and propose new equation. In order to exam the accuracy of the proposed equation and to find appropriate ways to improve, the recommended test also designed in chapter 5.
