“Analysis and design of Pre Engineered Buildings for industrial shed”
In structural engineering, a pre-engineered building (PEB) is designed by a PEB supplier
or PEB manufacturer, to be fabricated using best suited inventory of raw materials available
from all sources and manufacturing methods that can efficiently satisfy a wide range of structural
and aesthetic design requirements. as is becoming increasingly common due to the reduced
amount of pre-engineering involved in custom computer-aided designs, so it is also known as
simply Engineered Metal Buildings (EMB).
Pre-engineered building is an assembly of I-shaped members, often referred as I-beams.
In pre-engineered buildings, the I beams used are usually formed by welding together steel plates
to form the I section. The I beams are then field-assembled (e.g. bolted connections) to form the
entire frame of the pre-engineered building. Some manufacturers taper the framing members
(varying in web depth) according to the local loading effects. Larger plate dimensions are used in
areas of higher load effects.
Typically, primary frames are 2D type frames (i.e. may be analyzed using two-
dimensional techniques). Advances in computer-aided design technology, materials and
manufacturing capabilities have assisted a growth in alternate forms of pre-engineered building.
For design a pre-engineered building, engineers consider the clear span between bearing
points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection
criteria, internal crane system and maximum practical size and weight of fabricated members.
This design is done by computer aided system using software like STADD .PRO.so that we get
accurate load calculation and check suitability of sections.
An efficiently designed pre-engineered building can be lighter than the conventional
steel buildings by up to 30%. Lighter weight equates to less steel and a potential price savings in
structural framework. This new technique is widely adopted in industrial sector.

INTRODUCTION
1.1 Project Motivation:
Steel industry is growing rapidly in almost all parts of the world. The use of
steel structures is not only economical but also eco friendly. Here we refer “Economical”
with respect to time and cost. This can be Achieved by the application of Pre Engineered
Buildings.
1.2 Project Objectives:
• To study pre engineered building.
• To prepare a model of P.E.B.
• To analyze structure using Stadd 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.
1.3. Present theories and practices:
Pre Engineered Buildings are nothing but steel buildings in which excess steel is avoided
by tapering the sections as per bending moment requirements. In Pre Engineered Buildings total
design is done in factory and as per the design. All the required components are assembled and
erected with nut bolts thereby reducing the time of completion.
1.4 Project Features:
 Pre Engineered Building system is Computer assisted and designed to create a building
for specific use
 The complete building system is Pre Engineered to facilitate easy production and
assembly on site.
 Colour coating is given on top surface for bright appearance with colour with customer’s
choice.

.
1.5 Advantages of Pre Engineered Building:
 PEB System is zero maintenance & superior in strength than conventional.
 Lower Cost.
 Quality Control.
 Large Clear Spans.
1.6 Project Applications:
• Ware houses
• Factories
• Workshops
• Offices
• Gas stations
• Vehicle parking sheds
• Show rooms
• Aircraft hangers
• Schools
• Sports and recreational facilities
