Pre-Engineered Buildings (PEBs) have emerged as an efficient structural solution for industrial warehouses due to their superior performance in long-span applications, reduced construction time, and material efficiency. This study presents a comprehensive finite element–based analysis and optimal design of a steel warehouse structure using STAAD.Pro software in accordance with Indian Standard codes. The structural model is developed by considering realistic geometric configurations, loading conditions, and boundary constraints. Dead loads, live loads, and wind loads are applied as per IS 875, and member design is carried out following IS 800:2007 provisions. Various steel sections, including tapered members and bracing systems, are evaluated to achieve material optimization while satisfying strength, stability, and serviceability requirements. The structural response in terms of deflection, shear force, bending moment, and stress distribution is critically examined. Results indicate that the adoption of tapered sections and optimized bay spacing significantly reduces steel consumption without compromising structural safety. The study demonstrates that pre-engineered steel warehouses offer an economical, sustainable, and structurally reliable alternative to conventional steel buildings, particularly for large clear-span industrial structure
