Abstract

In the present paper, results of experimental investigations on the flexural strengthening of reinforced concrete beams using prestressed carbon-fiber-reinforced polymer (CFRP) laminates with near-surface mounted (NSM) method are presented and compared with the results of non-prestressed and non-strengthened specimens. Flexural strength tests of concrete using simple beams with center-point loading are conducted and crack propagation, mid-span load-deflection curves, ductility coefficient, energy absorption capability, and failure modes are discussed.
