Concrete laterally confined with fibre-reinforced polymers (FRP): experimental study and theoretical model
Blog Article
This paper Flexiti presents the findings of an experimental and analytical study of concrete cylinder behaviour when wrapped in fibreglass or carbon fibre-reinforced polymers (FRP).Compression testing was conducted on normal (30 MPa) and high (70 MPa) strength confined and unconfined concrete cylinders measuring 150 x 300 mm.The stress-strain relationship was evaluated in both cases.The findings showed that strength and ductility rose with FRP confinement.The experimental findings were used to develop an analytical model for predicting the stress-strain behaviour of FRP-confined concrete.
A comparison of the experimental and analytical results Accessories revealed that the model can satisfactorily predict the stress-strain behaviour and ultimate compressive strength of the concretes studied.
