Title: Strengthening of post-tensioned and reinforced concrete beams by bonding external steel plates
Author: Luo, Weimin
Issue Date: 1993
School/Discipline: Department of Civil Engineering
Abstract: This is a preliminary study of both post-tensioned, reinforced concrete beams that were strengthened by bonding external steel plates to their soffits, and reinforced concrete beams that were strengthened by bonding plates to their sides and soffits' Four post-tensioned plated beams, in which the degrees of the prestressing forces were varied, were tested to failure. A computer program was developed to carry out parametric studies on this type of beam. The results of the analytical models were compared with the experimental test results. Thirteen plated reinforced concrete beams were tested to failure in shear. Conditions varied consisted of: the thickness of the soffit plate, the length of the side plate, the thickness of the side plate and the areas of the tensile reinforcement. The effects of these parameters on the shear strength of reinforced concrete beams and their debonding moments were investigated.
