Study of Pre-Engineered and Conventional Steel Structure: A Review

Pre-Engineered Buildings (PEB) have gained significant importance in recent years due to their structural efficiency, economy, and reduced construction time compared to Conventional Steel Buildings (CSB). This paper presents a comparative study between a Pre-Engineered Building and a Conventional Steel Building using STAAD.Pro structural analysis software. Both structural systems are modeled with identical geometry, span, bay spacing, support conditions, and loading parameters to ensure a fair comparison. Dead load, live load, wind load, and seismic load combinations are applied as per Indian Standard codes IS 875 (Parts 1–3) and IS 1893 (Part 1). The comparison is based on parameters such as steel consumption, bending moments, shear forces, axial forces, storey displacement, and base shear. The results indicate that PEB structures provide significant reduction in steel quantity due to the use of tapered built-up sections while satisfying strength and serviceability criteria. The study concludes that Pre-Engineered Buildings designed using STAAD.Pro are more economical and structurally efficient than Conventional Steel Buildings.
