PEB construction have lot of advantages over conventional RCC structures or other industrial buildings.

2. INTRODUCTION
 Pre-Engineered Buildings can be adapted to suit a wide
variety of structural applications, the greatest economy will
be realized when utilizing standard details. An efficiently
designed Pre-Engineered Building can be lighter that the
conventional steel buildings by up to 30%.
 Tailor made building based on client’s requirement &
actual design calculations using tapered sections.
 Designing and casting is done in factory, building
components are brought to site then fixed/jointed at
the site. All connections are bolted.

3.  These are the structures basically produced at the factory
with high tensile steel material by collecting complete
information of the shed/building (viz; Length, Width,
Height etc,).
 The entire design of column, rafters and other accessories
is based on International structural standards and involve
high technical welding and quality production.
 Video- How drawing is drawn using STRUCAD?

4. Insulation (PEBI)
 Uniformly textured inorganic glass fibers bonded together
by a non-water soluble and fire-retardant thermosetting
resin. It is free from coarse fibers and shot due to its
mineral composition.
 PEBI is non-toxic and not hazardous to health.

6. Design Criteria
 DESIGN METHOD: Allowable stress design method is
used as per the AISC specifications.
 DEFLECTIONS: Unless otherwise specified, the
deflections will go to MBMA, AISC criteria and standard
industry practices.
 PRIMARY FRAMING: Moment resisting frames with
pinned or fixed bases.

7.  SECONDARY FRAMING: Cold formed Z sections or C
sections for purlins or girts designed as continuous beams
spanning over rafters and columns with laps.
 LONGITUDANAL STABILITY: Wind load on building
end walls is transferred through roof purlins to braced bays
and carried to the foundations through diagonal bracing.
 DESIGN SOFTWARE
The latest software that is used for design is STAAD 2007.

8. ERECTION SYSTEM
 Preparation for Erection
2. Pre Erection checks
3. Receiving Materials at site
4. Unloading Containers
 Erection of the Framing
7. Preparation of the First Bay
8. Main frames
9. Mezzanine floors
10. Crane Beams

9. Sheeting & Trimming
 Sheeting preparation
 Sheeting the walls
 Sheeting the roofs
 Miscellaneous trimmings
 Fascia

10.  Self weight  Self weight
30% lighter More heavy
 Primary Member is  Primary members are
tapered section Hot rolled “I” section
 Secondary members  Secondary members are
are light weight rolled “I” or “C” section
framed “Z” and “C” which are heavy in
section weight.

11.  Delivery – average 6 to 8  Delivery- average 20 to
weeks 26 weeks
 Foundation-simple design,  Foundation- expensive,
easy to construct & light heavy foundation
wt. required.
 Erection cost and time-  Erection cost and time-
accurately known 20% more than PEB

12.  Overall price - Higher
 Overall price -30%lower
price per square meter.
 Architecture-achieved at
 Architecture- achieved at
low cost
higher cost
 Erection process is easy,
 Erection process is slow
fast, step by step
and extensive field labor
is required.

CONCRETE BUILDINGS

14. APPLICATIONS
 Industrial Buildings
 Warehouses
 Commercial Complexes
 Showrooms
 Offices
 Schools
 Indoor Stadiums
 Outdoor Stadiums with canopies
 Gas Stations
 Metro Stations, Bus Terminals, Parking Lots
 Primary Health Centers, Angan wadi’s
 And many more…

15. Industrial Indoor Stadiums

16. Aircraft Hangars Metro Station
Wear house High rise Building

17. ADVANTAGES
 Aesthetic Appeal
 Faster Completion
 Economical
 Seismic Resistance
 Ease of Expansion
 Maintenance Free
 Large Clear Spans
 Controlled Quality

18. CONCLUSION
 PEB concept has been very successful and well established
in North America, Australia and is presently expanding in
U.K and European countries. PEB construction is 30 to
40% faster than masonary construction. PEB buildings
provide good insulation effect and would be highly suitable
for a tropical country like India.
 The pre-engineered building calls for very fast construction
of buildings and with good aesthetic looks and quality
construction. Pre-engineered Buildings can be used
extensively for construction of industrial and residential
buildings.
