Pre Engineered Building (P.E.B.)s are revolutionizing how modern industrial and commercial construction takes place, providing incredible efficiencies in terms of structural performance, cost, and fast-track delivery. This paper gives a systematic structural analysis and design of PEB systems having seven different span configurations (24 m to 60 m) with state-of-the-art software tools such as STAAD. TL: Pro V8i, SAP2000 v24, ETABS 2022, Tekla Structures A series of load combinations of seven LRFD-based equations according to IS 800:2007 and IS 875 (Parts 1–3) were applied to 49 structural models. The optimization process (iterative section selection combined with IS 800:2007 serviceability and strength provisions resulted in average reductions in steel weight of 17.3% to 25.2% compared to traditionally designed sections. Maximum deflection, lateral drift ratio, natural frequency, and member utilization ratios were studied as structural response parameters on the basis of which the modal matrix was established. SAP2000 v24 provides higher accuracy (97.8% member utilization accuracy) and capability in automating this than anything we have found. Statistical analysis corroborated a 21.5% (σ = 2.87%) mean reduction of steel and a 13.3% coefficient of variation, demonstrating the strength of the proposed optimization framework. In comparison to eight previous studies, the comparative analysis confirms the significantly higher efficiency of this approach as shown in its advantages of up to 9%-6% lower material utilization versus classical design approaches. These results provide an excellent evidence base for practitioners and researchers who are working on the design of PEB under Indian loading codes. |
