Abstract

This paper experimentally and numerically investigates the effect of strengthening circular steel tubes with cutout using Carbon Fibre Reinforced Polymer (CFRP) under compression. Tests were performed for unstrengthened and strengthened specimens and the results were compared to the numerical data. The numerical study was then extended through designing nine strengthening layouts with various CFRP layers and orientations and the results were compared aiming to find optimal solutions in remediation of the capacity. It was found that utilising CFRP in certain locations with specific dimensions and layers transfers the stress concentration from critical areas, hence remedies the lost capacity resulted from the presence of the cutout.
