Abstract

Abstract

The objective of this study is to investigate the flexural behaviors of reinforced concrete beam with nearsurfacemounted (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 amount of GFRP bars on flexural behaviour are studied further． The studies indicate that not only yield and ultimate load of the beam are significantly enhanced，but also the flexural stiffness in the yield and ultimate behavior state of the beam is improved by using NSM-GFRP bars． The studies also show that there has a beneficial contribution to restriction on crack propagation．
