Abstract
Repair and strengthening of steel bridges with CFRP materials. The International Energy Agency estimates that the direct CO2 emissions resulting from crude steel production are approximately 1.4 t of CO2 per ton of steel produced. To meet the Net-Zero 2050 targets, the steel industry must take significant steps to reduce greenhouse gas emissions. One effective approach to achieve this goal is to promote the repair or reuse of existing structures, thereby lessening the demand for crude steel production. The utilization of carbon fibre-reinforced polymer (CFRP) composites has demonstrated considerable potential in extending the lifespan of steel structures. This study addresses the primary distinctions in design requirements for CFRP strengthening of steel members. Furthermore, it provides an overview of research conducted on non-prestressed/prestressed bonded/unbonded strengthening systems employing CFRP plates and rods for steel girders, plates, and connections. Additionally, the study explains a few examples of aging steel bridges that were strengthened by the developed retrofit systems using CFRP materials, showcasing the real-world implementation of these advancements.
