Damage Assessment of Concrete Bridges With Different Dimensions under Loading

Evaluation of the behavior of concrete bridges under variable loading, especially in the design of bridges with different span lengths, is of high importance for ensuring structural safety and durability. In this study, a concrete bridge with fixed cross-sectional dimensions was analyzed in three models with span lengths of ۱۰, ۱۲, and ۱۴ meters. Simulations were conducted using Abaqus software, and the dynamic response of the bridge including stress distribution, displacements, and load concentration was examined. The results indicate that as the span length increases, the maximum stress on the bridge decreases and the load is distributed more uniformly along the structure, while displacements increase relatively. These findings highlight the significant effect of span length on the behavior of concrete bridges and its importance in the design process and in assessing structural safety and durability. The results can provide valuable guidance for optimizing the design of concrete bridges with varying spans and predicting their performance under different loading conditions.
