2. Framed Industrial Building:
• Framed buildings are building structures formed by the framed
elements usually in the form of columns and beams, as well as further
strengthened as necessary by the introduction of rigid floor
membranes and external walls.
Common forms of framed building structure subdivided into 3 main
types
• 1. Insitu RC frame
• 2. Prefabricated frame
• 3. Structural steel frame
3. Types of Framed Industrial Building:
Frames structures can be differentiated into:
1. Rigid frame structure
Which are further subdivided into:
•Pin ended
•Fixed ended
2. Braced frame structure
Which is further subdivided into:
•Gabled frames
•Portal frames
4. Framed Industrial Building
Framed structures are easily erected from pre-made members.
These members are easily connected together in the correct
sequence to form the structural framework.
Problems arise when large members are used and when the height of
the structure makes lifting difficult.
In these situations a crane will be needed to lift the members into
place.
Rectangular frames are usually made from steel but they may also be
made from concrete
5. Framed Industrial Building
• A framed structure is a network of beams and columns joined up to
form the skeleton framework of the building.
• The structural frame carries the total load of the building and
transfers it to the foundation.
• Cladding is fixed over the framework, or infill panels are placed
between its members, to totally enclose the space within the building
6. A Framed Industrial Building in course of
erection
Rectangular framed structures are used for
multi-storey buildings such as:
Office Blocks
Large Schools
Hotels
Hospitals or other similar buildings where a
multi-storey structure is required.
The floor space will incorporate a large number
of columns.
8. Principle factors affecting choice of frame
Principle factors affecting choice of frame
Structural Design consideration :
• 1 Foundation consideration
• 2 Standardization of members or design
• 3 Span and floor loads
• 4 Fire resistance requirement
• 5 Maintenance consideration
• 6 Integration of architectural & structural elements
9. Principle factors affecting choice of frame
Principle factors affecting choice of frame
Production consideration :
• 1. Availability of materials
• 2. labour and plant
• 3. Speed of construction
• 4. Availability of mechanical plants
10. Principle factors affecting choice of frame
Architectural Design consideration
• 1. Size and shape of site
• 2. Conditions of site
• 3. Integration of mechanical elements
• 4. Architectural or aesthetic requirements
11. Bracings:
• The horizontal and vertical bracings, employed in single and multi-
storey buildings, are also trusses used primarily to resist wind and
other lateral loads.
• These bracings minimize the differential deflection between the
different frames due to crane surge in industrial buildings.
• They also provide lateral support to columns in small and tall
buildings, thus increasing the buckling strength.
• Braced frames resist the wind and seismic forces, much more than
non-braced buildings.
• Steel bracing is economical, easy to erect, occupies less space and has
flexibility to design for meeting the required strength and stiffness.
12. Building configuration
• Typically the bays in industrial buildings have frames spanning the width
direction. Several such frames are arranged at suitable spacing to get the
required length
• Depending upon the requirement, several bays may be constructed
adjoining each other.
• The choice of structural configuration depends upon the span between the
rows of columns, the head room or clearance required the nature of
roofing material and type of lighting.
• If span is less, portal frames such as steel bents or gable frames can be
used but if span is large then buildings with trusses are used.

16. SIMPLE CONNECTION
Simple connections are assumed to transfer shear only shear at some nominal
eccentricity. Therefore such connections can be used only in non-sway frames where
the lateral loads are resisted by some alternative arrangement such as bracings or
shear walls.
22. Advantageous features of Framed Industrial
Building:
Advantageous features of framed structure
• 1. Speedy construction due to simplicity in geometry – consist of only
columns and beams (or partially by the floor slab) as the main structural
elements
• 2. Very rigid and stable – able to resist tremendous vertical (dead load) and
lateral loads (wind)
• 3. Reduced dead load – absent of thick shear wall etc.
• 4. Roofed over at an earlier stage – every floor slab being finished becomes
an cover to protect the lower floors from sun and rain
• 5. Offer large unobstructed floor areas – without obstacle between
columns
• 6. Flexible utilization of space
23. Advan. features of Framed Industrial Building:
(continued) .
• 7. Adaptable to almost any shape
• 8. Easily altered within limits of frame – regular or non-regular grid
system is very adaptable in spatial arrangement
• 9. Offsite preparation possible – especially for prefabricated
construction using precast concrete or structural steel elements
• 10. May be designed to accommodate movement
• 11. Acceptable distribution of natural light – window openings can be
provided easily on eternal walls
• 12. Easy to design structurally including computer design – again, due
to simple geometry
24. Disadvantageous features of Framed
Industrial Building:
Steel frame constructions do have a couple of disadvantages, the
most regularly cited being:
• 1) Thermal Conductivity: Steel is not known for its warmth, due to its
high efficiency in conducting heat. The insulation value of walls can
be reduced by as much as half when heat is transferred away through
steel studs, which is not good news for energy retention in a building.
Where steel frame construction is used, insulation measures need to
be put in place to counteract the thermal conductivity of steel.
• 2) Reduced Flexibility On Site:
One of the benefits of using wooden structural components is the
ability to adjust them on site. A component can be cut down to size,
nails hammered in to strengthen the join and so on. This obviously
can’t happen with steel.
25. Disadvantageous features of Framed
Industrial Building:
• Contd.
The measurements of steel need to be precisely calculated in advance,
because a steel fabrication is delivered to site in its final form, ready to
be slotted into the building. This is of course one of the big advantages
of Steel
• 3) Supporting Structures:
Steel frame constructions rarely work on their own. They usually
require drywall, sheathing, insulation and supplementary wooden
components to bring a building together.
