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

This study presents a numerical investigation into the structural behavior of a single-span concrete bridge with a clear span of ۸ meters, subjected to a concentrated vertical load of ۲۰۰ kN applied at the mid-span. The research focuses on evaluating the bridge’s response, specifically examining the stress distribution and vertical displacement characteristics, considering a bridge deck thickness of ۳۰ cm. Utilizing Finite Element Analysis (FEA), the structural integrity and performance of the bridge system are assessed under the specified loading conditions. The results provide critical insights into the displacement patterns and peak stress concentrations within the concrete deck, offering a foundation for evaluating the structural safety and serviceability of single-span bridge configurations under heavy concentrated loads. The findings highlight the significant influence of the deck geometry on the load-bearing capacity and overall structural stiffness.
