Abstract- Construction projects involve multiple critical decisions, among which the selection of an appropriate structural system plays a vital role in ensuring efficiency, economy, and performance. Industrial shed structures are widely used in manufacturing, storage, and logistics sectors, where large column-free spaces and cost-effective solutions are essential. Traditionally, Conventional Steel Buildings (CSB) have been used for such applications; however, with advancements in structural engineering, Pre-Engineered Buildings (PEB) have emerged as a modern and optimized alternative. The present study focuses on the comparative analysis of shed-type structures, specifically PEB and CSB systems, to determine the most efficient structural solution. The analysis is carried out using STAAD Pro V8i software, considering various parameters such as span (5 m to 40 m), height (4 m to 10 m), and loading conditions as per relevant Indian Standard codes (IS 800, IS 875, and IS 1893). The structures are analyzed under dead load, live load, wind load, and seismic load conditions, with wind load considered as the governing factor. The results obtained from the analysis include key structural parameters such as bending moment, shear force, axial force, deflection, and steel weight. These parameters are systematically compared to evaluate the structural performance of both systems. The study reveals that PEB structures exhibit lower bending moments, reduced axial forces, and significantly lesser deflection compared to CSB structures. Furthermore, PEB systems demonstrate 20% to 30% reduction in steel weight, leading to considerable savings in construction cost and improved efficiency. The findings indicate that PEB structures provide better structural performance due to the use of tapered built-up sections and optimized design, whereas CSB structures, with uniform sections and truss configurations, result in higher material consumption and internal forces. Additionally, PEB structures offer advantages such as faster construction, improved durability, and sustainability. Based on the comparative analysis, it can be concluded that Pre-Engineered Buildings are more economical, efficient, and suitable for modern industrial shed construction, particularly for long-span applications.
