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...

Fiber reinforced polymer (FRP) laminates are being successfully used for strengthening of existing reinforced concrete structures. Bond of the FRP reinforcement to the concrete substrate is of critical importance for the effectiveness of the technique. In this project, flexural test specimens were prepared to address some of the factors expected to affect bond, namely, bonded length, concrete s...

Fiber Reinforcement Polymer(FRP) has been widely accepted as an innovative material for renovation and strengthening of existing infrastructures. Among the FRP materials, the Poly-p-phenylene benzobisoxazole (PBO) fiber sheets attracted great attention in recent years because of the high strength, high Young modulus and high energy absorption capability. In this study, a PBO Prestressing Upgrad...

To improve the ductility and seismic performance of a double coupling beam, authors applied polyethylene terephthalate (PET) sheet steel tube to form fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular (DST) composite beams. A low-cyclic reversed experimental program was carried out which factored in member form, diameter, construction methods. The results indicate that energy dis...

The aim of this study is to investigate the influence fiber reinforcement polymer (FRP) on shear behavior concrete (RC) beams with various guidelines. FRP thickness, beam depth and strength at ultimate load are considered as main parameters. A finite element (FE) by using ANSYS computer program was used analyze reinforced beams. numerical models were effect depth, strength, CFRP sheet configura...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...

The development and application of new Fiber Reinforced Polymer (FRP) material 3D printing construction technology provide a basis for making up the shortcomings traditional thin-shell structures building with better performance. In this paper, Printing Composite (3DPC) structure is proposed, which prepared using FRP plate as permanent base mold combining it cement technology. Both typical expe...
