dc.description.abstractThis study examined the behaviour of beams reinforced with FRP composites using the finite element software ANSYS [1]. The use of FRP sheets to strengthen existing concrete beams is gaining popularity in the construction/rehabilitation industries. FRP laminates as strengthening materials offer numerous advantages including: 1) high strength/self-weight ratio 2) corrosion resistance, 3) resistance to ultraviolet radiation, 4) durability, 5) ease of installation, and 6) design flexibility. CFRP strengthened beams could gain as much as two times the strength of unstrengthened beam, along with a moderate increase in stiffness. Although GFRP laminates offer minimal improvement in stiffness, they costs less than CFRP in many countries, which makes it viable alternative in retrofitting seismic damage [2]. Mohamed and Khattab [3] studied the response of beams strengthened with CFRP sheets applied at optimal locations and configurations, and concluded that the flexural strength and stiffness of the strengthened beams were higher than unstrengthened beams. Jayajothi [4] developed finite element models and predicted enhanced flexural capacity of reinforced concrete beams with FRP laminates bonded to the tension face. Leung [5] conducted an experimental program to study the flexural and shear behaviour of concrete beams externally strengthened with GFRP plates and observed enhanced strength and ductility of the strengthened beams. Leung [5] also noted a reduction in deflection when GFRP plates are bonded simultaneously on the bottom and on the sides of deficient reinforced concrete beams. Choobbor [6] developed finite element models validated with experimental data at all stages of loading and concluded that FRP strengthening of beams increases strength and ductility.en_US
