Abstract
A convenient and efficient method for strengthening and stiffening existing reinforced concrete beams is to adhesively bond steel plates to their surfaces. However, tests have shown that adhesively bonded plates tend to peel away prematurely due to flexure and shear. Flexural peeling can be prevented by terminating the plate at a region of zero moment, in which case the plate is prone to shear peeling which is the subject of this paper. Eight tests on the shear peeling of side-plated beams are described, and design procedures are developed for predicting the shear peeling resistance. These procedures can be used to ensure that reinforced concrete beams that are retrofitted by adhesive bonding steel plates to their sides do not debond prematurely.
