摘要：
This article presents an experimental study on the effectiveness of CFRP strengthening method on the flexural behaviour of Reinforced Concrete beams. Six identical RC beams with dimensions of 80 x 140 x 1100 mm are cast and statically loaded to complete flexural failure in this study. The specimens are divided in three categories, including: Two beams without strengthening as control specimens (Group 1), two intact beams strengthened with CFRP sheets (Group 2), and two pre-cracked beams strengthened using CFRP sheets (Group 3). The strengthening effects on the stiffness and ultimate strength, together with flexural behavior of test beams are discussed in detail based on the test results.
