Abstract
Flexural and bond–slip behaviour of fibre reinforced polymer (FRP)-reinforced concrete beams are investigated experimentally and numerically in this paper. Four-point bending tests are carried out to study the flexural and bond–slip behaviour of FRP-reinforced concrete beams reinforced with carbon FRP, glass FRP, and basalt FRP rebars with different surface conditions. The flexural and bond–slip behaviours of the test beams are also studied numerically by employing the recently developed finite element models with and without bond–slip effect. The results obtained from the numerical modelling agree very well with those obtained from experimental studies. Parametric study is carried out to investigate the effects of different rebar surfaces and rebar types on the structural behaviour of the FRP-reinforced concrete beams.
