The actively prestressed strengthening technique of CFRP plate is a kind of strengthening technology with great application in the future. After a comparison and conclusion of the advantages and disadvantages of various prestressed tensile techniques for CFRP plate from home and abroad, based on the WSGG anchor, this paper puts forward the hinged anchor and a new technique where the hinged anchor tensions in vertical direction, the biggest characteristic of this technique is to ensure force uniformity of CFRP plate, consequently, high strength feature of CFRP plate can be fully developed. In addition, a series of improvement have been achieved, such as on-site baiting, fast clamping and rapid tensioning, etc. of CFRP plate. Hinged anchor and its prestressed tensile technique are firstly applied for the reinforced projects of Chongqing Xiaojia River Bridge and Chongqing Lianhua River Bridge, which promote rapid strengthening for the old bridges successfully.

Fibre reinforced polymers (FRP) are being used extensively in the rehabilitation and retrofitting of existing structures  as an external reinforcement because of their properties like high strength to weight and stiffness to weight  ratios, corrosion resistance, light weight and high durability. They are especially used in the reinforced concrete structure like bridges, chimney, high rise building etc. At present FRP reinforcements are available in the form of reinforcing bars and are used in the structures in place of steel, mainly the structures are constructed near the coastal areas or in the aggressive environments. The main advantage of FRP rebar is its corrosion resistance, light weight, durability and easy handing. The FRP rebars are being used worldwide for many structures including bridge structures as well, but not well explored because of its availability. The main objective of this thesis work is to assess the static load behaviour of RC T-beams reinforced internally with GFRP reinforcements using finite element analysis software ANSYS. Totally twelve numbers of specimens were considered in this study with varying parameters such as type of reinforcements, reinforcements ratio and concrete grade. Modelling of the T- beams were done with ANSYS using solid 65 and link 8 element and the same were analyzed under static loading conditions. The results obtained from the ANSYS were compared with the theoretical and experimental analysis. Based on the comparison suitable conclusions and recommendations are made in this research work.

As one kind of the advanced composite materials (ACM), FRP is now getting widely used in civil engineering for its advantages as light weight, electromagnetic isolation, high strength, fatigue resistance and corrosion resistance. This article wants to provide a quality control method for the FRP cables by eliminating its unwinding effect error. Firstly, two FRP-OFBG (Optical Fiber Bragg Grating) cables were fabricated in factory, and then the two specimens were tested by the MTS (material test system). Secondly, theoretical understandings with boundary conditioned formulas were provided for analysis on the unwinding process of the cable. After that the unwinding displacement of the FRP-OFBG cable was obtained by using the b-value method. Finally, a service ability assessment of the cable was given before the conclusions.
