CHARACTERISTICS AND CALCULATION METHODS OF CONCRETE BEAM STRENGTHENED WITH INMOUNTED CFRP-PCPs

Abstract

Abstract: Experimental studies on eight reinforced concrete beams strengthened with near-surface mounted(NSM) CFRP-PCPs reinforcement have been tested with load. Comparing with plastering CFRP to strengthen prestressed, the technique to strengthen concrete beams with near-surface mounted CFRP-PCPs reinforcement has specialties as rigidity. In addition, according to the test load-deflection relation curves, under the the identified trilinear moment-curvature model, deducing the CFRP-PCPs reinforcement embedded in reinforced concrete beam deflection calculation formula, the calculated value was compared with the test results, and the results match well.

Key words: CFRP-PCPs composite bars, trilinear moment-curvature model, deflection, concrete beam
