AGED TRANSPORT CONCRETE BRIDGES FATIGUE RELIABILITY IS EVALUATED USING PROBABILISTIC FRACTURE MECHANICS
India's transport system is the country's most important mode of transportation. Over a million important bridges, the majority of which are concrete bridges, focusing on concrete bridges, fatigue is frequently a significant issue and is one of the key variables influencing their lifespan. The goal of the current study is to use a linear elastic fracture mechanics approach to detect cracks in old simply supported slab bridge and T-beam bridges and assess their reliability index and likelihood of failure. The methodology is used to determine the reliability index and the appropriate number of cycles. The outcomes were utilised to construct an inspection plan after computing an acceptable risk level. This technique offers a rational basis for calculating the reliability index or chance of failure for any concrete bridges, and it may also be used to determine the ideal inspection interval.
