The Analysis of Bonding Shear Stress of Affixed Reinforced RC Beams

Abstract:

Bonding a strengthening plate to the tension face is an effective technique to repair reinforced concrete beams; however, much large shear stress along the adhesive line at the plate end will occur. The stress may cause the plate bonded at its end and the strengthened beams fail prematurely. In this paper, the finite element analysis software ANSYS was applied to study the interfacial stress distribution among the adhesive layer. The main factors affecting the peak values of the interfacial stress was also investigated entirely. The effect depends on two factors such as the distance of plate end from the support and plate thickness.
