Performance of Fiber Reinforced Composite Strengthened Concrete Interface

The finite element method was adopted for investigation, the effects on the performance of the fiber reinforced polymer composite materials strengthened concrete structure. The finite element formula was conducted in terms of Mindlin first order shear deformational theory. And then the effects of the bond layer length, the width and numbers of bond layers adhesive fiber reinforced polymer on the the interfacial performance were discussed. Numerical results show that bond layer parameters of FRP strengthened concrete interface can affect adhesive performance.
