CONCEPT, DESIGN & CONSTRUCTION

PRE ENGINEERED STEEL BUILDINGS

PRE ENGINEERED BUILDINGSPRE ENGINEERED BUILDINGS

The buildings are design as per client’s requirement & actual design calculations using tapered sections.

A combination of built up section, hot rolled section, cold formed elements and profiled sheets

Designing and casting is done in factory

Building components are brought to site

Then fixed/jointed at the site All connections are bolted.

Steel was very expensive item in USASteel was very expensive item in USA The concept of PEB originate from here.The concept of PEB originate from here.

GUIDELINES FOR PEB DESIGN AT PROPOSAL STAGE

All Designs Shall Be As Per MBMA [Metal Building Manufacturer Association] &Client Specifies As Per Is Code.

Live load as Per American Code = 0.57 KN/M2 and as Per IS Code = 0.75 KN/M2. (Reduction in live load to be incorporated for buildings having higher slopes)

In American Design , Wind Coefficients To Be

Followed As Given In MBMA.

In Is Design, Internal & External Building Wind

Coefficients As Per Is -875 (Part-3).
