Analysis and Design of Pre-Engineered Building Structure Using Staad.Pro

Abstract – This paper presents a comprehensive analysis and design study of a Pre-Engineered Building (PEB) structure using STAAD.Pro, a structural analysis and design software widely used in civil engineering. PEBs have gained significant traction in modern construction due to their modularity, faster erection time, and cost-effectiveness compared to conventional steel structures. The objective of this study is to evaluate the feasibility, material optimization, and structural performance of a PEB industrial shed located in Chennai, India. The structure was modeled and analyzed under various loading conditions including dead load, live load, wind load, seismic load, and collateral load, following IS 800:2007, IS 875 (Parts 1–3), and IS 1893:2016. The design incorporated tapered sections for the primary frames and cold-formed members for purlins and girts. Seismic and wind loads were particularly critical due to the site's location in Zone III and a basic wind speed of 50 m/s. The final STAAD.Pro output confirmed that the structure remains within permissible deflection limits and achieves material economy through optimization. This paper demonstrates that PEBs provide a viable, efficient, and sustainable alternative for industrial infrastructure development.
