Investigation of RC Beams Rehabilitated with Angle-Ply Composite Laminate Plate

This parametric study investigates the RC Beams Rehabilitated with angle-ply composite laminate plate [θn/90m]_s. This work is based on a simple theoretical model to estimate the interfacial stresses developed between the concrete beam and the composite with taking into account the hygrothermal effect. Fibre orientation angle, effects of number of 90° layers and effects of plate thickness and length on the distributions of interfacial stress in the concrete beams reinforced with composite plates have also been studied.
