The increasing demand for efficient and safe construction practices in riverine environments has led to the widespread use of temporary steel platforms for infrastructure development. This paper presents the design and analysis of a steel finger platform bridge constructed over a river to facilitate crane operations, material handling, and equipment movement during construction. The study focuses on the structural behaviour of a pile-supported steel platform subjected to dead load, live load, heavy crane loading, wind forces, and water current effects, designed as per IRC 6:2017 and IS 800:2007. A three-dimensional model was analysed in STAAD.Pro to evaluate load distribution through deck panels, main girders, cross beams, and bracing systems, and to determine governing bending moments, shear forces, and stresses. Results show that crane loading, particularly the 150T crawler crane during front lifting, governs the design and produces the maximum stresses in the deck panels and main beams. All structural components-deck panels, beams, bracing members, and bolted connections-were found to be within permissible limits. The study concludes that steel finger platforms offer an efficient, economical, and structurally reliable solution for temporary access in bridge construction projects.
KEYWORDS
The study confirms that the designed steel finger platform is structurally safe under all considered loading conditions, including dead load, live load, crane load, piling rig load, wind load, and water current effects. STAAD.Pro analysis demonstrated acceptable stresses, reactions, and deflections for the heavy construction equipment operating on the platform. Crane loading, particularly front lifting of the 150T crawler crane, was found to govern the design, producing the maximum forces in the main beams (axial 47.7 t, Fy 66.5 t, Mz 58.17 t-m) and deck panels. The adopted steel sections, bracing systems, and bolted connections provide adequate strength and stability, and the structure satisfies the relevant IRC and IS code provisions for temporary bridge systems. Proper construction planning and periodic maintenance remain essential for safe field performance. Future work may extend this study through finite element modelling, fatigue analysis, and digital structural health monitoring to further improve reliability.
