Abstract

n

nGantry girders serve as critical structural elements in industrial facilities such as steel plants, workshops, and heavy manufacturing units, where electric overhead traveling (EOT) cranes operate. The design of these girders is governed by stringent codal provisions to ensure safety under bending, shear, and deflection. However, discrepancies between codal predictions, analytical formulations, and finite element analysis (FEA) results, particularly under variable wheelbase and dynamic impact loads, have been widely reported. This review consolidates research spanning three decades on codal validation, empirical analysis, STAAD/FEA modelling, and optimization strategies for gantry girders. Studies reveal that codal provisions, while ensuring safety, often result in conservative designs, particularly concerning deflection limits and impact allowances. Variable wheelbase significantly influences deflection, bending stress distribution, and fatigue behavior, yet limited codal guidance exists. Optimization frameworks, raging from empirical and codal-based methods to metaheuristic algorithms such as genetic algorithms (GA), demonstrate potential material savings of 10–25% without compromising safety. Serviceability, fatigue, and detailing considerations, including stiffeners, lateral-torsional buckling, and thermal stresses, have been explored in literature; however, current codal provisions remain underdeveloped. This paper critically reviews these contributons, identifies research gaps, and proposes future directions incorporating AI-driven design, digital twin modelling, and integrated codal-optimization approaches.nn
