Abstract
Both steel and polymeric fibers have been used to reinforced concrete and consequently increase its toughness and crack resistance. Fiber reinforced concrete can be used in some structural applications with a reduced amount or even without any conventional reinforcement. One of the application for fibers is to increase the load-carrying capacity of concrete subjected to shear. Several design methods have been proposed to increase the shear strength due to fibers. Each of the methods accounts for the fiber contribution by means of an index based on the toughness of the material. However, each formula uses a different index, obtained from different types of test configurations. Thus the application of the design methods can be difficult. Moreover, most of the design methods and test procedures have been developed only for the evaluation of steel fiber reinforced concrete.
