Title: Strengthening of Concrete Structures

Abstract:Although strengthening by bonded steel plates, where adhesive is used to bond the steel plates to the structural members, has been established for more than two decades, it was not until recently that this strengthening technique has been used in Singapore. A number of reinforced concrete structures have been successfully strengthened using this technique over the last three years. This paper describes this strengthening technique with particular reference to the material selection and design considerations, as well as the strengthening and construction methodologies. A case study on one of the structures strengthened is also presented. The structural members strengthened include bonding of steel plates to beams to increase flexural as well as shear capacities and encasing columns to prevent buckling and increased load carrying capacity.
