Abstract Concrete-filled steel tube (CFST) columns are widely used in civil engineering because of their excellent bearing capacity; however, the reinforcement CFST lacks effective measures. To strengthen quickly and effectively, two methods, namely, winding FRP (fiber reinforced polymer) or strips, were explored this work. Two unconfined columns, eight FRP-strengthened four welded strip-streng...

The first Fibre Reinforced Polymer (FRP) implemented to a UK Railway Bridge was in 2001, since then a number of key railway bridge projects involving FRP have seen completion; six being fully FRP bridges. Although the potential use of FRP on the infrastructure was found in 1998 due to high strength to weight ratio, stiffness and good chemical resistance, the implementation of FRP to small scale...

Abstract This paper presents a comprehensive experimental study on the behaviour of FRP-confined concrete in square and rectangular columns focuses some issues that might be addressed with view to improving predictive models. For this purpose, 31 prismatic specimens height 600 mm low- medium-strength (20–35 MPa) were tested under centred compression. The parameters studied aspect ratio between ...

As a composite material, the damping energy consumption mechanism of fiber reinforced polymer-confined concrete (FRP-C RC) structure is very complex. In previous dynamic calculation models, bond-slip effect for steel bars was often ignored, which would lead to considerable error in response FRP-C RC structures. this paper, new numerical model columns considering established using zero-length el...
