Abstract:
Pasting prestressed fiber reinforced composite (FRP) sheets to reinforce and repair civil building structures can improve engineering efficiency. Starting from the theoretical analysis, the calculation formula of the interface layer of the prestressed FRP sheet reinforced RC beam is derived, the shear stress distribution of the interface layer between FRP sheet and concrete under prestress is analyzed, and the carbon fiber sheet (CFL) reinforced RC beam is verified by numerical experiment by finite element. The effects of initial prestress, FRP sheet thickness and interfacial layer thickness on interfacial shear stress were discussed.
