PRE – ENGINEERED ENGINEERED STEEL BUILDINGS
T. Khaja Rasool V. Lila Srinivas Reddy Mohammed Moiz S. Venkatesh
Introduction •
Pre-Engineered Buildings can be adapted to suit a
wide variety of structural applications. •
All the components are produced in a factory on basis of structural and aesthetic requirements.
•
These components are made in modular (or) completely Knocked down condition.
Introduction •
Manufactured
materials
are
transported
and
assembled in the customer site. •
Manufacturing and Production processes like cutting
and welding is not done at the customer site. •
An efficiently designed Pre-Engineered Building can be lighter that the conventional steel buildings by up to 30%.
Technical Parameters of PEB •
Breadth, width or span of the building.
•
Length of the building.
•
Roof slope.
•
Design Loads.
•
Bay spacing.
•
Type of Frame.
•
Sub Systems.
Main Components of PEB Anchor bolts: These are embedded
•
into the foundation.
Main Components of PEB Primary components: Primary components include Columns and Rafters •
Secondary Components: Secondary components include Purlins, Grits and Eaves •
Main Components of PEB
•
Sheeting or Cladding: Corrugated or Galvanized sheets are used as sheeting
Main Components of PEB •
Accessories: Accessories include Sky lights, Wall lights and Turbo Ventilators.
Advantages of PEB •
Optimised design of steel reducing weight
•
Architectural Versatility
•
Light weight
•
Quick Project completion
•
Less cumbersome at site
•
Good Seismic resistance
•
Easy future expansion
Advantages of PEB •
Architectural Versatility
•

High Rise Buildings
• Self weight 30% lesser
• Self weight more heavy
• Primary member is Tapered section
• Primary member is Hot rolled section
• Secondary members are light weight rolled framed “Z” and “C” section
• Secondary members are “I” or “C” section which are heavy in weight.
• Delivery – average 6 to 8 weeks
• Delivery- average 20 to 26 weeks
• Foundation-simple design, easy to construct & light wt.
• Foundation- expensive, heavy foundation required.
• Erection cost and timeaccurately known
• Erection cost and time20% more than PEB
Market Potential • PEB is relatively a new concept in India and were introduced to markets lately in 1990’s. • The market potential of PEB in India is 12 lakh metric tonne and growing at a compound rate of 25 to 30%.
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 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.
