Abstract:

This paper presents the experimental investigation conducted on cold formed steel built up box shaped beams strengthened using CFRP. Box shaped cross sections were made of connecting two channel members using screws. The selected beam specimens were 300mm, 400mm and 500mm in length with screw spacing of 100mm and edge distance of 50mm. Firstly, Single point load bending test were carried out to determine the maximum load, deflection and failure modes for plain sections. Secondly, same bending test were repeated for CFRP wrapped sections to determine the maximum load, deflection and failure mode. The maximum load capacities calculated using AISI specifications are compared with experimental maximum loads which are in good agreement.
