Structural Analysis of the First Iron Bridge in the World Using the Finite Element Method

Modern numerical simulations using the finite element method have revealed critical insights into the structural behavior of the Iron Bridge, the world's first iron bridge, located in the UNESCO World Heritage Site of Ironbridge Gorge. The analysis predicted that the maximum tensile stress occurs in a strut near the bridge's midpoint, likely explaining its failure. Additionally, the numerically predicted deformations in the bridge's circles and ogees align with observed deformations, validating the model's accuracy. These findings underscore the invaluable role of advanced simulations in guiding conservation and maintenance efforts for this historic structure.
