• Abstract:
  Tied arch bridges represent a vital component of the nation's infrastructure, valued for their structural efficiency and aesthetic qualities. These bridges rely on arch ribs to transfer vertical loads into horizontal thrusts, which are counteracted by the tie beams (TBs) acting in axial tension. In addition to this axial tension, TBs are also subjected to strong axis bending mainly due to live loads from vehicular traffic. The TB, therefore, is a critical structural component, maintaining the internal equilibrium of the system by resisting the spreading forces generated by the arch and bending caused by the moving vehicular loads. These TBs are often constructed as built-up steel members, a design that inherently possesses a degree of internal redundancy, allowing them to redistribute loads among their components following a localized fracture.
