Abstract:
Design for deflection control is a critical part of the design of FRP reinforced members due to the relatively low modulus of elasticity and elastic-brittle nature of FRP reinforcement. This paper provides an overview of design for deflection control including a brief review of the basic mechanics of beam flexure and a review of methods to account for cracking, tension stiffening, shrinkage and creep. The basis for selecting appropriate deflection control criteria is also discussed and a framework is presented to incorporate deflection control into the overall design process.
