Research output: Contribution to journalArticlepeer-review


The objectives of this study were twofold. The first was to investigate the compressive and flexural behaviors of small-sized concrete specimens strengthened with sprayed fiber reinforced polymer (SFRP), considering various fiber lengths, fiber volumes, and concrete strengths. The second was to evaluate the strengthening effects of SFRP on the flexural behaviors of large-sized reinforced concrete beams. U-shaped strips and shear keys were applied to the test specimens to improve the interfacial bond resistance between the concrete surface and SFRP.
