Abstract - In current years, introduction of Pre Engineered Building (PEB) in the design steel of structures has facilitated in enhancing design. Application of PEB in place of Conventional Steel Building (CSB) resulted in many advantages, including economy and simple fabrication. Long Span, column free structures are the greatest crucial requirements in any type of industrial structures and Pre EngineeredBuildings(PEB)satisfiestheserequirementalong with reduced time and cost in comparison with conventional structures. The PEB methodology is advantageous not just because of its high-quality pre-design and prefabrication, but also due to its lightweight nature and cost-effective construction. This study includes analysis and design of industrial structure in accordance with the Indian standard. The economy of structure is conferred in terms of its weight comparison, between Indian code. The proposed study is to analyze frames of industrial shed for different loadings by using PEB sections. Comparison between Conventional and PEBstructuresisalsoperformed.Analysisof industrialshedis done for various Loading conditions by Conventional Steel Building & by PEB structure. The B.M., Shear Forces and Stresses have been compared for Conventional Steel Building and PEB structures and required section are designed.

Whenitcomestoconstructionprojects,choosingbetween pre-engineered and conventional steel structures has significantimpactoncosts.OneofthemainbenefitsofPEBs is their standardized components and factory fabrication. This results in lower cost compared to conventional steel structures. Additionally, the construction time is reduced duetothecomponents,leadingtolowerlabourcosts.PEBs are designed to optimize steel, making them more costeffective than traditional. The efficient design of PEBs ensures that there is minimal wastage of steel, further reducing costs. While conventional steel structures highly customized and complex projects, whether it's for warehouses, industrial buildings, PEBs are cost-effective needsofvariousconstructionprojects.Withlowermaterial andlaborcosts,reducedconstructiontime,andoptimized use of steel, PEBs are a professional choice for a wide. In additiontocostsavings,PEBbuildingsarealsolighterand fastertoconstructthantraditionalsteelbuildings.PEBroof structures are almost 30% lighter than conventional steel buildings, which not only saves its costs but also its foundation. This lightweight design can lead to additional savings. PEB construction is 30% to 40% faster than traditional steel building methods,allowing projects to be completed more quickly and efficiently.
