Abstract - Pre-engineered buildings (PEBs) are structures
that have been pre-engineered by a manufacturer to be
constructed using a predetermined inventoryofraw materials
and manufacturing techniques that may effectively fulfil a
variety of structural and aestheticallypleasingdesigncriteria.
Mezzanine floors, canopies, fascias, internal partitions, and
other structural accessories can be added to pre-engineered
steel buildings. The buildings can also be waterproofed using
specific mastic beads, filler strips, and mouldings. Pre-
engineered structures with efficient designs can be up to 30%
lighter than traditional steel structures. Less steel is required
when something is lighter, which might reduce the cost of the
structural structure.
Key Words: pre-engineered building (PEB), conventional
steel buildings, mezzanine floors, canopies, fascia;
1.INTRODUCTION
India is a developed country. Large-scale housing
construction is taking place all over thecountry.Becauseher
30% of India's population lives incities.Therefore,morewill
be built in urban areas. Pre-engineered steel structures are
manufactured or manufactured in-house. Components are
manufactured accordingtocustomerrequirements.Detailed
components are laid out and numbered in specific locations,
but cannot be changed. Because the rod is made from the
point of view of design function. These components are
manufactured modular or completely disassembled for
transportation. These materials are shipped tothecustomer
site and set up. We do not perform welding or cutting at the
customer's site. There is no manufacturing process at the
customer's site. Pre-engineered Buildings (PEBs) are
designed by manufacturers to be manufactured using
predetermined inventories of raw materials and
manufacturing methods that can efficiently meet a wide
range of structural and aesthetic design needs. In some
geographic industries, these buildings are also called pre-
engineered metal buildings. Historically, the primary frame
structure of pre-engineered buildings is an assembly of I-
shaped members, often called I-beams. I-beams are
commonly used in PEB by welding steel plates together to
form an I-beam. The I-beams are then assembled on site
(such as bolted joints) to form the overall frame of the pre-
engineered building. Cold-formed Z-shaped and C-shaped
members can be used as secondary structural members to
attach and support siding. Building exteriors can be roll-
formed profiled sheet steel, wood, upholstery, precast
concrete, masonry blocks, glass curtain walls, or other
materials.

2. LITERATURE REVIEW
An extensive study of literatures is carried out to
understand the concept of sequential analysisandtheeffects
of it on structure. In addition to this, literatures related to
structural load path irregularitiesarereviewedand behavior
of structure is understood.
2.1 Review of Literatures
1. Zende, et. al. [1] dealt with comparative study ofanalysis
and design of Pre-Engineered-Buildings and conventional
frames. Staad Pro software has been usedinordertoanalyze
and design Pre-engineered building structures and
conventional structures, authors considered 3 examples. In

the first example, a 3D model of a Hostel building has been
designed and compared with conventional structure using
conventional steel. It is seen that the weight of tapered PEB
sections are 369.24kN whereas for conventional building, it
is found to be 491.64 kn. Pre-Engineered Building weighs
25% less than that of conventional building. In the second
example, a 2D plane frame of width 44m for both PEB and
conventional has been designed and comparison has been
made in terms of weight of steel. PEB structure is designed
for a clear span of 44m without any column in between, as
not in case of conventional frame, where it is not possible to
provide a clear span truss and hence an interior column is
provided. It is noticed that, even though PEB structures
provides clear span, it weighs 10% lesser than that of
conventional buildings. Some examples of how your
references should be listed are given at the end of this
template in the ‘References’ section, which will allow you to
assemble your reference list according to the correct format
and font size.
2. Pérez [2] dealt with design and analysis of an industrial
steel building. Limit states, stability check. Work done by
authors focused on the design of a structural steel industrial
building of double-T type section located in an industrial
area of Valladolid (Spain). Firstly, a linear analysis was
carried out in past to dimension the structureandcheck that
it resists according to the established regulations, the
Technical Building Code, the national adaptation of theEuro
codes. In the second place, a nonlinear analysis isperformed
with the objective of verifying the Ultimate Limit State of
stability of the structural elements and of the industrial
building as a whole.Authorssummarizesthemethodologyof
the nonlinear analysis of the spatial structures of beams,
which allows problems of instability with bending and/or
torsion deformations to be solved, calculating the critical
moment of lateral buckling for any load case and support
conditions.
3. Sai Kiran et al. [3] studied the Comparison of Design
Procedures for Pre-Engineering Buildings. The economy of
the structure is discussed in terms of its weight comparison,
between Indian codes (IS800- 1984, IS800-2007) and
American code (MBMA-96), and between Indian codes
(IS800-1984, IS800- 2007).Themaindifferencebetween the
Indian Code (IS800- 2007) to the other equivalentAmerican
Codes are in the classification of thecross-sectionofthesteel
member. As per Indian code, the classes of section
considered for design are Plastic, Compact and Semi-
compact, slender cross-section. It is well known that many
PEB manufacturers usesectionswithverythinwebsinorder
to reduce the weight of the section and be
economical/competitive in their commercial offers, and
these thin webs do not satisfy the codal provisions of IS800:
2007.
2.2 Research Gap
╸Sufficient literature is available on analysis and design of
PEB structures, but using same sizes of flanges of element
effectively It will definitely help to achieve great economy of
project which ultimately affect overall project. Hence more
attention is required towards this issue.
╸Available literatureshowsthat,foranalysis,mostlyuniform
flange profile is used while it is not necessary at every
moment hence it will be more realistic to use section with
full capacity.
3. METHODOLOGY
Metal construction of pre-engineered can be optimized to
meet specific design criteria. Recent days, most Indian
consultants and his PEB Vendors providers largely follow
Indian and American design practices.
The design cycle consists of the followingsteps:1.Setsection
sizes and brace locations based on the geometry and loads
specified in the frame design. 2.Calculate the moment, shear
force, and axial force at each analysis point for each load
combination. 3.Compute the allowable compressive and
tensile shear, axial and bending stresses at each analysis
point. 4. Based on the actual andallowablestresses,calculate
the corresponding shear, axial, and bending stress ratios,
and calculate the bond stress ratio. 5. Design the optimal
splice site and ensure that the predicted size meets
manufacturing constraints. 6. Usepassoptimizationmodeto
achieve optimal pass depth for next cycle and update
member data file. 7. At the end of every design cycle, an
analysis is performed to achieve optimization of the flange
brace. Rigid frames.
Frame Geometry: The program has the ability to handle
different types of frame geometry, such as: Rigid frames,
frames with multipleinternal columns,singleslantedframes,
slanted frames, etc. Frames with different spans, different
heights, different slopes, etc. H. Articulated supports, fixed
supports, subduction supports, and supports with a certain
degree of freedom. Asymmetric frames, such as off-center,
unequal modules, or different slopes. Custom purlin and
flange spacing and flange brace locations.
Design Codes: Contains the service requirements that the
design must meet. Implementation standards for design
loads (other than earthquakes)ofbuildingsandstructures.It
helps determine these loads on the buildingbeing measured.
The key design codes commonly used are: AISC: American
institute of steel construction manual AISI: American iron
and steel institute specifications MBMA: Metal building
manufacturer’s code ANSI: American national standards
institute specifications ASCE: American society of civil
engineers 35 UBC: Uniform building code IS: Indian

standards (IS1893-2002 PART 1 FOR EQ) and (IS 875
PARTIII FOR WIND).
4. DESIGN PHILOSOPHY
The design under consideration is an industrial shed with a
free span of 35 meters. The shed was designed in 3D using
STAAD software, with the load he distributed evenly across
the three coordinate systems. H. Simulate X, Y, Z correctly.
Dead, live, wind, temperature, earthquakes, etc. were
considered when designing the frame. It has a structurethat
can receive the wind load caused by the opening and closing
of the large shed door both in the closed state and the open
state. Load calculations areperformedinthesamewayasfor
normal frames. The(DL+WL)or(DL+LL)conditionisusually
the key case driving the design because the PEB slope is
small (e.g., 1 in 10). Support conditions are usually fixed,but
selective use of fixed conditions can be advantageous,
resulting in a combination of base plate and anchor bolts. In
the pivoted base state, the section typically tapers
downward and is bolted to the base. All other connections
are usually designed as rigid connections and steel
connections are moment connections that transmit axial,
moment and shear values between the connected sections.
Wind load calculations should refer to IS-875 pt.3 latest
edition to achieve design wind pressure after careful
analysis and combination of internal and external pressure
or force coefficients. Appropriate load combinations with
wind loads, seismic loads and crane loads should be
considered. The basic idea of rigid frame design is to employ
a "fixed" or "pinned" strut basecondition.Asturdystanchion
base is a stable frame at all times and helps control the
allowable deflection (lateral fluctuation) of the frame. Steel
designers always prefer fixed base frames to fixed base
frames. On the contrary, foundation design becomes a
nightmare for foundation planners, especially for buildings
with large spans. In a fixed base design, the frame is rigid,
but heavy moments are transferred to the foundation. Weak
ground makes foundation design a tedious task. Similarly,
with pinned supports, the frame does not transfer moments
to the foundation, only vertical and horizontal reaction
forces affect the design of the foundation.Itlookssimple,but
due to the long span, controlling the frame deflection with a
pinned base is a difficult task. Combined stresses are
typically checked using interactive software that calculates
section utilization efficiency and compared to limits (LSD or
WSD). H. An actual stress/allowable stress of 0.95 means
that the section is used to 95% of its strength. For this, the
total weight of the frame is calculated. Many such that the
sections are designed with variables such as flange
thickness, web thickness, flange width, web depth, etc. so
that the whole frame is theoreticallysafeandhasa minimum
weight. Trail runs. Deflection testing is the next step. The
easiest way to control this deflection is to increase the
geometry/section size of the frame, but that would increase
the overall building tonnage, which would increase not only
the seismic force but also the later cost, so it is not
recommended. Not recommended. I need a solution that
allows me to control frame sway and does not increase the
section size. The best method we have been able to find is to
"brake" the frame to control excess deflection. In this
example, stiffeners (reinforced eaves) were installed at the
height of the eaves on both sides of the structure in the
longitudinal direction. The span of this eaves brace is
approximately L/10 on each side. In the example below, you
can see how eaves braces can be very helpful in controlling
horizontal deflection,makingfoundationdesign easier.Some
vendors use 90% of the sections and leave 10% for possible
manufacturing, transportation, assembly and assembly
errors. But this competition has led people to believe that
there is no problem anywhere! The next important step is to
design the weld between the flange and the web. Again, the
efficiency of the weld seam plays an important role.
Therefore,PEBmanufacturersavoidon-site weldingbecause
a 4.5mm weld in the workshop may be better than a 6 or
8mm weld in the field. The next step is to design the field
joints (where the parts will be assembledonsite).Theforces
produced at the joints are known. Bolted connection
preferably perpendicular to the plane of the frame to utilize
the tensile capacity of the BM bolt instead of shear capacity.
Therefore, the number of screws required for connection is
reduced. Many span reduction and lateral support
techniques such as sag bars, knee bracesand pull barscanbe
used to optimize the section.

6. CONCLUSION
1. From study, It has been found that by IS code, we need to
provide more material weight than the American code
(AISC).
2. The major reason for weight reduction is due to different
section classification clause in code.
3. By using AISC code we can use more thinner section as
compared to IS code, as AISC code allows thinner section by
their section classification for primary members.
4. Also in general practice of industry, uniform size flanges
are used which are not necessary because if different size
flanges are used, it will cause reduction in the weight and
will bring down cost of the project.
