Abstract

A practical technique for flexural repairing of exterior beam-column joints using CFRP wraps is presented. The procedure is to restore the flexural capacity of the damaged joint. An experimental study is conducted in order to evaluate the performance of a 1:2.5 scale reinforced concrete external beam-column joint sub-assemblage belonging to an OMRF RC structure (Ordinary Moment Resisting Frame) designed to Australian Concrete Code, and then repaired using the proposed technique. The beam-column joint is tested under monotonic load applied at the free end of the beam and under a constant axial column load. The proposed repair procedure is applied to the tested specimen. The Unidirectional CFRP sheet system proved to be effective in upgrading the flexural capacity of the damaged beam-column joint. Comparison between the behaviour of the specimen before and after repair is presented and the results are checked against a non-linear finite element analysis using ANSYS.
