Analysis of R C Beams Strengthened With F R P Plates

Many factors affect the strength and ductility of beams strengthened with fiber-composite plate to address the effect of some of the basic variables the present paper focus on the objectives

(1) To present analytical model that predict the stresses and deformation in the concrete beams strengthened with epoxy- bonded fiber- composites plat. simplified analytical methods are presented to predict stresses and deformations in rectangular and T-beams strengthened with epoxy bonded FRP-plated.

The strains and stresses in the FRP plate, steel rebar and concrete as well as the curvature at midspan are calculated using an incremental deformation technique described in the following. For the convenience of calculation, strain in the extreme fiber of concrete, rather than the load, is increased in specified increments to generate the moment curvature curves.
