3. Objectives
 To study pre engineered building.
 To prepare a model of P.E.B.
 To analyze structure using Staad Pro.
 To design sections, connections etc.
 To study the effect of P.E.B. for following issues:
To reduce complexity on site.
To achieve accuracy.
Speed of work.

4. Pre Engineered Building
 Steel buildings in which excess steel is avoided by
Tapering the sections.
 Tapering is done as per Bending Moment
requirements.
 Components are manufactured in factory and
assembled on site.
 Larger plate dimensions are used in areas of higher
load effects.

7. Elevation

9. Problem statement
 Internal dimensions of building: l=60 m, b=15 m
 Height of building up to eaves level= 6 m
 Location of building= Islampur (pune region)
 Type of roofing = G.I.sheets
 Area of opening (permeability of building 5% to 20%)
 Angle of rafter = < 100
 Spacing between two columns = 6 m
 Number of frames = 10

10. Load calculation
 Dead load:
1. Wight of purlin :5 kg/m2
2. Weight of sheeting :5 kg/m2
Total weight :10 kg/m2=0.1kN/m2
3. Self weight of tapered section

11. Live load
 Live load =0.75 kN/m2 (Angle lesthan 10 0)
= 0.75*6
Live load =4.5 kN/m2
 Collateral load:
Collateral load = 0.2* 6 =1.2 KN/M

Load combination of strength:
 (D.L.+L.L.)*1.5+1.05 *C.L.
 (D.L.+W.L.S.)*1.5
 (D.L.+W.R.P.)*1.5

 (D.L.+L.L.)*1.2+1.05*C.L.+0.6* W.R.S.
 (D.L.+L.L.)*1.2+1.05*C.L.+0.6* W.P.P.
 (D.L.+L.L.)*1.2+1.05*C.L.+0.6* W.P.S.

14.  Load combination of serviceability:
 (D.L.+L.L.+C.L.)*1
 D.L.* 1+(L.L.+C.L+W.L.P.)*0.8
 D.L.* 1+(L.L.+C.L+W.L.S.)*0.8
 D.L.* 1+(L.L.+C.L+W.R.P.)*0.8
 D.L.* 1+(L.L.+C.L+W.R.S.)*0.8
 D.L.* 1+(L.L.+C.L+W.P.P.)*0.8
 D.L.* 1+(L.L.+C.L+W.P.S.)*0.8

20. Results Sl. No. Description PEB CSB
1 Steel Take Off (kN) 12.194 84.595
2 Support Reaction (kN) 10.62 375.582
3 Maximum deflection (mm) 39.48 8.611
4 Maximum Shear Force (kN) 66.894 453.981
5 Maximum Moment (kNm) 175.52 908.577

21. Advantages
 PEB System is zero maintenance & superior in strength
than conventional.
 Lower Cost.
 Quality Control.
 Large Clear Spans.
 strict quality control environment, thereby ensuring
superior quality & finish.
 Easier to incorporate future expansions

22. Disadvantages
 Not used for multi-storey building.
 Technical person is required on site.
 Special Machinery is required.
 Design of member takes more time.

23. Conclusion
 Using of PEB instead of CSB may be reducing the steel
quantity.
 Reduction in the steel quantity definitely reducing the
dead load.
 Reduction in the dead load reducing the size of
Foundation.
 Using of PEB increase the Aesthetic view of structure.

24. Applications
 WARE HOUSES
 INDUSTRIAL SHEDS
 FACTORIES
 WORKSHOPS
 OFFICES
 GAS STATIONS
 VEHICLE PARKING SHEDS
 SHOW ROOMS
 AIRCRAFT HANGERS
 SCHOOLS
 SPORTS AND RECREATIONAL FACILITIES
