This study examines the behavior of circular concretes externally confined by green sustainable WHBR FRP containing water hyacinth fiber ropes and bio-resin. principally purposes to discover axial stress-strain relationship FRP-confined concrete. A total 10 with a dimension 150×300 mm were cast, strengthened one four layers FRP, tested under compression. The stress deformability observed be inc...

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...

The use of fiber reinforced polymers (FRP) for reinforcement of aging and deteriorating concrete members has emerged as a viable and cost effective alternative to traditional repair and strengthening techniques to upgrade deficient structures to meet today’s design standards (Crasto et al., 1996; Myers et al., 2000). The load carrying ability of structures such as beams and columns can be enhan...

S Jacketing technology using fiber reinforced polymer (FRP) composites is being applied for seismic retrofit and rehabilitation of reinforced concrete (RC) columns designed and constructed under older specifications. In this study, the authors develop an electromagnetic (EM) imaging technology for detecting such damage as voids and debonding between the jacket and the column, which may signific...

The current paper reviews existing design guidelines for strengthening beams in shear with carbon fibre reinforced polymer (CFRP) sheets and proposes a modification to Concrete Society Technical Report TR55. It goes on to present the results of an experimental programme which evaluated the contribution of CFRP sheets towards the shear strength of continuous reinforced concrete (RC) beams. A tot...
