Experimental study of continuous reinforced concrete beams strengthened or repaired by composite materials

Abstract

In this work, the programme consists of six continuous (three-span) beams with overall dimensions equal to (250 × 150 × 9000) mm, the examined RC beams were arranged into two groups; each group has one
control beam which was not strengthened and loaded up to failure. This RC beam damaged 100% corresponding to ultimate strength after that was repaired by used two types of composites materials: carbon
fibre for group A and glass fibre for group B. The third RC beam of each group was directly strengthened and loaded up to failure. In this study, the strengthening or repairing effects by using composite materials on the ultimate strength, mechanical behaviours of continuous RC beam with three spans was analysed and discussed.
