Abstract / Description of output

Carbon fibre-reinforced epoxy intumescent coatings are a common method of fire protection for steel structures in industrial facilities and are particularly widespread in oil and gas installations. This paper examines the impacts of these composite coatings on the structural performance of steel beams at ambient temperature and investigates the potential for utilising the associated flexural response enhancements for structural strengthening of deficient steel elements at ambient temperature, in addition to thermally protecting them in an accidental fire. Results from bending tests on protected steel beams are presented, demonstrating the feasibility of increasing the moment capacity of Isections with structurally enhanced composite epoxy intumescents. Their hybrid functionality for enhancing the load carrying capacity of steel elements at ambient temperature and providing them with thermal protection in a fire suggests a strong potential for use as an engineered fire-safe system for structural strengthening of steel flexural elements.
