Box culverts are very important part of a transportation network as they provide an economical alternative to heavy bridges. Box culverts do not require a separate extensive foundation system and they are ideally suited for medium spans. Structurally, box culverts are complicated structures as they are buried completely in soil and because of their self-stabilizing nature. Hence, there is need to for a detailed parametric study on multi-cell box culvert structures in order to understand their structural behavior and to study the influence of various parameters effecting its structural behavior. In the present study span to height ratio of the culvert is analyzed by taking 3D analysis and dynamic vehicular analysis result is compared to a simplified static analysis. An attempt is made to carry out a parametric study on the behavior of a multi cell box culvert subjected to dead loads as well as IRC wheel loadings. The box culverts are modelled using STAAD.Pro software using effective width method. IRC 70R loading is used for the analysis and design of culverts. The results of the study reveal that dynamic study has significant influence on the result of the analysis and should be carefully considered. One of the key parameters influencing the design and performance of box culverts is the span-to-height (S/H) ratio, which governs the geometric proportions and consequently affects the distribution of internal forces, deformation behavior, and material consumption. In addition, dynamic vehicular loads, resulting from traffic movement, impose cyclic and transient forces that can significantly influence the culvert’s structural performance, particularly in long-term serviceability and fatigue life. This work provides a foundation for future investigations and the development of more resilient design practices for culvert-type bridge structures in earthquake-prone areas.
