Interfacial Shear Calculation of Concrete Beams Strengthened with FRP Plate under Temperature and Creep Effect

Abstract:

Concrete beam reinforced with FRP plate has many advantages—high bearing capacity, light weight, fast construction progress, corrosion resistance, etc. The collaborative work between FRP and concrete is achieved through the binder, so the interface of them is the weak link. Under external loads, the interface of FRP-concrete will emerge inevitable internal force redistribution, and the FRP plate is a kind of resin material and its physical and mechanical properties will change with temperature and time. In this paper, using energy method, the differential equations of interfacial shear, meanwhile considering temperature and creep effect of FRP plate strengthening concrete beams were established. And the calculating formulas of interfacial shear under different loads were given.
