Paper Title:
Study on Debonding Failure Behavior of RC Beams Combination Strengthened with Carbon Fiber Reinforced Polymer and Steel Plates
  Abstract

In order to investigate the debonding failure mechanism,the distributions of interfacial shear stress between cracks and the influence of preload of on the ultimate load and interfacial shear stress,one reference beam and five beams strengthened with CFRP and steel plate at different level of perload were tested and analyzed.The experimental result indicated that the perload level has less influence on the ultimate capacity.Moreover,when debonding failure of sheet-end interface of concrete beams strengthened with CFRP and steel plate is avoided,the debonding failure of reinforced beams at perload level will occur in the position of midspan.At last,on the basis of cross-sectional equilibrium and compatiable conditions,an analytical model of interfacial bond shear stress is obtained, meanwhile the analytic model favorably matched with the experimental results.
