| Abstract: | The objective of this study is to investigate the flexural behaviors of reinforced concrete beam with near-surface mounted(NSM) GFRP bars.The tests of a group of simply supported rectangular cross-section beams strengthened with NSM GFRP bars and two control beams are carried out.The mode of failure,load-deflection relationship,and load-strain curve of the all specimens are analyzed.Cracks propagation is discussed based on measured data.The two effect factors of ratio of steel reinforcement in the beam and ... |
