Structural Response of an ۸-m Single-Span Concrete Bridge with a ۳۰-cm Deck Slab under ۵۰ kN Distributed Vertical Loading: A Case Study

This study investigates the structural response of an ۸-meter single-span concrete bridge with a ۳۰-cm thick deck slab subjected to a ۵۰ kN vertical distributed load. A detailed finite element analysis (FEA) was performed using Abaqus to evaluate the bridge performance under the prescribed loading condition. The response was primarily assessed in terms of vertical displacement and stress distribution on the deck. The numerical results provide insight into the effects of distributed loading on stiffness behavior and stress localization, which are essential for evaluating the serviceability and safety of short-span concrete bridge decks. The findings of this case study can support design optimization by clarifying how deck thickness interacts with distributed load magnitude to govern deflection and stress levels.
