Analysis and Design of Pre-engineered Building Structure Using SAP2000

Nowadays, pre-engineered building (PEB) structures are getting very popular globally. These type of structures are manufactured in factory and erected on site. Also, these structures are economical, eco-friendly and recyclable. PEB heavy structures need advanced software like SAP2000 for analysis and design. The objective of the current study is to check performance of PEB structures. The parameters used for analysis and design are bay spacing, frame spacing, wind analysis and earthquake analysis. The bay spacings 5 m, 8 m and 9 m and the frame spacings 20 m, 35 m and 50 m are considered. Basic wind speed from 33 m/s to 50 m/s is selected for wind analysis and zone III is selected for seismic analysis. The design is carried out by using Indian Standard Code 800:2007. The comparison of the PEB structures and conventional steel building (CSB) structures has been determined on the basis of weight of the frame sections, sway and deflection of the steel frames. The result shows that, percentage of weight reduction of PEB structure is about 30% to 40% compared with CSB structures. Result of sway analysis shows that the span length increased from 20 to 50 m gives less deflection, and also in earthquake analysis PEB structures shows less deflection compared with CSB structures. The study concludes that PEB structures are economical, light weight and safe than CSB structures.
