26 Fatigue strengthening and lifetime extension of steel structures with bonded CFRP and SMA materials
The International Energy Agency estimates that direct CO2 emissions due to crude steel production is approximately 1.4 tons CO2 per ton steel produced. In order to achieve the targets of Net Zero 2050, steel industry has to reduce the greenhouse gas emissions. An effective approach to reach this target is to practice repair or reuse of existing structures to reduce the demand for crude steel production. Application of shape memory alloys (SMAs) and carbon fibre-reinforced polymer (CFRP) materials has shown a great potential for lifetime extension of steel structures. In this work, the principle of fatigue strengthening using SMA and CFRP materials are discussed. Different prestressed bonded and unbonded systems are presented. Finally, a few different applications of fatigue lifetime extension of steel bridges are presented.
