Rational Method for Calculating Deflection of Fiber - Reinforced Polymer Reinforced Beams

摘要

This paper presents a rational and relatively simple method for pre - dicting deflection of fiber - reinforced polymer (FRP) reinforced con - crete members. The method is based on the integration of the moment-curvature relation, which is assumed to be trilinear. The relationship is based on the assumption that the moment - curvature relation of a cracked FRP reinforced member remains linear under increasing load, and that tension stiffening is negligible.
