Partial Interaction Model of Flexural Behavior of PVA Fiber–Reinforced Concrete Beams with GFRP Bars

Abstract

This paper describes experimental and analytical investigations on a highly durable composite structural system comprising polyvinyl alcohol (PVA) fiber-reinforced concrete (PVA-FRC) reinforced with glass fiber-reinforced polymer (GFRP) bars. To aid in the development of a design guideline for this novel composite beam system, a generic analytical approach that is equally applicable to both conventional concrete and FRC beams reinforced with steel or FRP rebar is applied. Predicted load-deflection and load-crack width responses are compared to the experimental results, showing very good correlation for the flexural behavior of PVA fiber–reinforced concrete members.
