Abstract

Some of existing CONCRETE structures have some deficiencies due to low material quality or design. In recent years, the retrofit of nonresistant or damaged reinforced CONCRETE members with external bonding of fiber-reinforced-polymer (FRP) laminates has received considerable attention. The objective of this study is to examine effects of glass-fiber-reinforced-polymer (GFRP) composite rehabilitation system on the reinforced CONCRETE BEAMs. Experiments were conducted on BEAMs with and without GFRP composite sheets on their tensile surfaces. A total of 16 BEAMs were tested. 8 BEAMs were tested under static loading, while the remaining 8 BEAMs were subjected to cyclic loading.Specimens were 200*300*2000 mm reinforced CONCRETE BEAMs with enough transverse reinforcement to avoid shear failure. The main parameter in the test study was the number of layers of GFRP laminates. The experimental results show that, bonding GFRP laminates improves both flexural capacity and stiffness of BEAMs. Moreover it reduces the quantity and width of cracks, and limits the destruction in rapture zone. Evaluation of load-deflection curves shows the favorite behavior of strengthened BEAMs under cyclic loading. Results of different tests have very good agreement with the application of analytical equations.
