Abstract
<p>This paper presents flexural analysis of PET (PolyEthylene Terephthalate) fiber reinforced concrete using 3-D meso-scale analysis to verify reinforcement mechanisms in PET fiber. In this proposed model, fibers with a specific length and diameter are distributed as discrete entities within a specimen. In this work, it has been clarified that the proposed model can adequately simulate load- displacement relations obtained from flexural tests of PET fiber reinforced concrete. This paper also presents numerically investigations in order to assess the effects of fiber length and strength on flexural toughness.</p>
