Abstract

Abstract

It is described loading tests on rectangular cross section of RC beams under conditions of carbon fiber-reinforced polymer sheets'different bonded lengths and amounts, clear spacing of notch, intensities of RC and ratios of reinforcement as parameters. And the purpose of these tests is to study the distinct effects of these strengthening conditions on the strengthened RC beams'failure mode, change in stiffness, crack spread situation and ultimate bearing capacity. The experimental results show that the flexural bearing capacity and stiffness are increased effectively and propagation of cracks are reduced obviously by rehabilitation.
