摘要：

The suspension bridge is one of the most popular among the various kinds of large-span bridges. These bridges are resistant to earthquakes and have good spanning capabilities. They lessen the amount of foundation excavation and eliminate the requirement for high piers. As a result, when building large-span bridges, suspension bridges are the preferred option. Suspension bridges have geometrically complex structures and complex structural action, making the suspension bridge more challenging to design Engineers. The majority of previous researchers attempted to analyze suspension bridges using a closed-form solution. In this paper, static response of a multi-span suspension bridge with an orthotropic steel box deck is analyzed using the finite element method-based software ANSYS, when loaded with different cases of IRC loadings, and combinations of IRC 70R and IRC Class A. From the static analysis, the worst possible cases of deformation and stress due to different static load combinations were determined. The IRC 70 R wheeled ‘N’ type loading delivers the largest equivalent stresses (von-mises) and total deflection on deck (242.65 mm) in static responses under highway vehicle loading. The scope of the current investigation is confined to the structure's static analysis. This study, on the other hand, will facilitate designers in gathering the necessary information for further evaluation of the modal analysis and dynamic behavior of the bridge model as a result of various dynamic loads such as moving vehicle load, seismic load, wind load, blast load, and so on. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
