Abstract: During the last four decades, glass fiber reinforced concrete has increasingly been used in structural applications. It is generally accepted that the addition of glass fibers significantly increases tensile toughness and ductility, also slightly enhances the compressive strength. Several studies have reported previously the favorable attributes of glass fiber reinforced concrete (GFRC) on compression, tension and shear behavior. As the models proposed so far can, at best, describe only a few aspect of the GFRC with a given type and amount of fibers, establishing simple and accurate, generalized equations to describe the behavior of the GFRC in tension, compression and shear that take into account the fiber type and content is essential compression and shear that take into account the fiber type and content is essential. This research investigated the shear behavior of GFRC and to formulate ageneralize model for the ultimate shear strength of GFRC. Effect of the fiber volume fraction on the shear response of GFRC with optimum glass fiber content has been studied. Four different volume contents ranging from 0% to1.5% was used in the test specimens. Direct shear tests were conducted and finally, an equation model was proposed to predict the ultimate shear strength of SFRC in terms of glass fiber content.
