  9. 9. PEB Design
  10. 10. Pre Engineered Metal Building ( Major Components) <ul><li>Main framing or vertical columns </li></ul><ul><li>Purlins, girts and eave struts </li></ul><ul><li>Sheeting and insulation or prefab panels </li></ul><ul><li>Brick & Cement Board Walls </li></ul><ul><li>Flooring </li></ul><ul><li>Paints and finishes </li></ul><ul><li>False Ceiling </li></ul><ul><li>Miscellaneous services </li></ul>
  11. 11. MAIN FRAMING <ul><li>Main framing : It includes the rigid steel frames of the building. The PEB rigid frame comprises of tapered columns and tapered rafters. The tapered sections are fabricated wherein the flanges are welded to the web. Splice plates are welded to the ends of the tapered sections. The frame is erected by bolting the splice plates of connecting sections together . </li></ul>
  12. 12. PURLINS, GIRTS AND EAVE STRUTS <ul><li>Purlins, girts and eave struts are also known as secondary cold-formed members. </li></ul><ul><li>There is no welding involved in their preparation. They are prepared by just bending the steel coil giving it the desired shape (Z-shape for purlins and girts, and C-shape for eave struts). </li></ul><ul><li>Purlins : Purlins are the secondary members are for supporting the roof panels & wall cladding . </li></ul>
  13. 13. PANELS AND INSULATION <ul><li>Single skin profile or ribbed steel sheets are used as roof and wall sheeting, roof and wall liners, partition sheeting. The steel sheets are generally made from steel coils. Minimum thickness of steel coils used is 0.5mm high tensile steel. </li></ul><ul><li>The steel sheets are normally of zincalume or galvanized bare and permanently colour coated or plain which can be coated at site after installation. </li></ul><ul><li>These buildings can be properly insulated by providing fibrous insulation slabs / rolls of non- combustible Rockwool, Aluminium foil laminated, placed over a metal mesh bed created between the purlins, and then the roofing steel sheet fixed over it. The siding walls can also be insulated by providing a double skin profile or ribbed steel sheet or cement board sheets on inner side wall cladding having Rockwool Insulation slab sandwiched in between and held in position with the help of ‘Z’ spacers in between the two steel sheets. In similar pattern a double skin insulated roofing system can also be erected. The cement boards will give a conventional white finish after paining. </li></ul>
  14. 14. PANELS AND INSULATION <ul><li>Another alternative is to provide pre-fabricated insulated panels, which comprises of two single skin panels (plain steel sheets galvanized / zincalume colour coated) with polyurethane foam insulation in between. </li></ul><ul><li>These panels are intended for use as thermally efficient roof and wall claddings for buildings e.g. in high altitude areas and hilly terrains. Roof is of profile steel sheet with or without insulation fixed underneath. </li></ul><ul><li>False Ceiling of particle / rigid board is fixed to a steel frame work hung from the trusses. Insulation can also placed over the false ceiling packed in polythene. Here a 2 ft. high brick wall is required to be given on the outside for protection. </li></ul><ul><li>For walls a second alternative can be by way of normal brick work </li></ul>
  15. 15. PANELS AND INSULATION 2 <ul><li>The latest trend developed for construction of pre-fab single storeyed residential houses does not involve any steel structure (columns & purlins). </li></ul><ul><li>The walls are constructed with profiled GI sheet of high crest height and faced with cement particle boards and the crest depths filled with either high density Rockwool or Rigid insulation material like Polyurethane Foam or Expanded Polystyrene. </li></ul><ul><li>The roof is erected with trusses placed over the walls and profile sheet fixed to purlins and bolted to the trusses. </li></ul><ul><li>The corners of the walls are provided with steel flashings fixed to the profiled GI sheet on both sides before fixing of the cement particle boards. </li></ul>
  16. 16. PAINTS AND FINISHES <ul><li>Normally the primary and secondary steel are coated with one coat (35 microns) of redoxide paint without any special treatment to steel. However, if some special paint has to be applied to steel in order to give better anti-corrosion properties etc. then the steel members have to be shot-blasted and then coated with the special paints. </li></ul>
  17. 17. DOORS AND WINDOWS <ul><li>Steel or aluminum framed doors and windows are fixed to the purlins or the supporting profiled steel either by welding or bolted to the flanges already fixed to the purlins.. </li></ul>
  18. 18. Design Codes <ul><li>Design codes that govern the design procedures and calculations are as follows :- </li></ul><ul><li>Frame members (hot rolled or built-up) are in accordance with AISC (American Institute of Steel Construction) Specifications for the design, fabrication and erection of structural steel. </li></ul><ul><li>Light gauge cold-formed members are designed in accordance with AISI (American Iron and Steel Institute) Specification for the design of light gauge cold formed steel structural members. </li></ul>
