Abstract
Recently fiber-reinforced polymer (FRP) has become a practical alternative construction material for replacing steel bars as reinforcement in concrete structures to overcome the corrosion related problems. The recently developed basalt fiber-reinforced polymer (BFRP) is a valid alternative to carbon fibers for their lower cost and to glass fibers for their strength. However, the performance of Basalt reinforced concrete elements subjected to repeated loading, which is a critical design limit for bridge beams, has not been fully explored. Also the brittleness and low modulus of elasticity of BFRP greatly reduces the stiffness of BFRP-reinforced concrete (BFRPRC) beams. The aim of this experimental study is to investigate the flexural behavior of concrete beams reinforced with Basalt fiber reinforced polymer (BFRP) bars when they subjected to repeated loadings and to improve their stiffness. For this purpose an experimental program was set up on eight specimens consisting of pure Basalt FRPRC beams and hybrid BFRPRC beams with 2050 mm length and a cross-section of 150 x 200mm were carried out and tested under static or repeated loading followed by static loading up to failure. The results were discussed and analyzed. The test results indicated the contribution of adding steel reinforcement to concrete beams reinforced with BFRP bars. Finally some valuable conclusions and recommendations were given.
