Concrete beams strengthened with prestressed unbonded carbon‐fiber‐reinforced polymer plates: An experimental study
Source abstract
Abstract
This study addresses the applicability and effectiveness of prestressed unbonded carbon‐fiber‐reinforced polymer (CFRP) for strengthening concrete beams. Three‐ and four‐point flexural tests were conducted up to failure for 10 concrete beams. The cracking, yield, and experimental nominal loads of the prestressed strengthened beams increased with the prestress levels. However, the ultimate loads were similar regardless of the prestress level because beam failure was dominated by rupture of the CFRP plates. Based on the results, the recommended appropriate prestress level for securing the ductility of a prestressed strengthened beam is ≤40% of the tensile strength of the CFRP plate. POLYM.
