Abstract

This paper describes a numerical method for the full-range analysis ofprestressed concrete flexural beams strengthened with prestressed glass fiber-reinforced polymper (GFRP) sheets, focusing on Ductility and flexuralstrength behaviour. prestressing concrete structures cause increasedflexural strength of these structures thus increased resistance of structures, increased span length, and reduced displacements of beams are resulted, which is very effective and economically feasible. The study of Ductility ofthese structures that have been used a lot nowadays, has a great importancebecause it expresses the capability of structure in inelastic deformations before destruction of members. Present paper attempts to investigate the effect of prestressed GFRP sheets on Ductility and deformation of beamsstrengthened by this method. Regarding to this, the modelling of threesample of beams in different conditions was studied using Finite elementsoftware Ansys. After comparing the results of numerical analysis of concrete beam with GFRP sheet and the numerical results of two types ofprestressed concrete beam with wire and proofing the efficiency ofpresented model, the displacement and energy Ductility index, deformation, resistance and the amount of displacement of concrete beams have beeninvestigated. Three beams with 160mm*280mm*3600mm dimensions have been modelled. In summary, the results express that the application of prestressed GFRP sheet may cause the least displacements of beam and anincrease of 10% and 10. 4% will be achieved in the flexural stiffness and Ductility.
