Abstract


Traditional strengthening solutions of steel beams usually consist in supplementing the base material in specific locations, for which, certain parameters are not fulfilled any more. For the most common cases, these strengthening solutions imply large consumptions of construction materials and high costs. Strengthening solutions based on carbon fibre reinforced polymer (CFRP) composites have gained much interest in the last years, because of the superior mechanical properties of the latter and due to their simple and rapid technique of application. This paper presents the analytical evaluations of the flexural capacity of a steel beam which has been strengthened using a (CFRP) strip.

Keywords
