Building types and building components

1. What Is Building
A structure with walls and a roof standing
more or less permanently in one place is
commonly known as a building. For example a
house or factory. Buildings serve several
societal needs – primarily as shelter, living
space, privacy & security, to store materials,
workspace, etc. In this lecture in first part we
will discuss different types of buildings, and
than components of building will be
discussed.

2. Part 1
Types Of Buildings:
Types of buildings may be classified in two ways:
1. On the basis of its use,
2. On the basis of Structure.

3. Classification based on type of
use:
Depending upon the character of occupancy or the type of
use, buildings can be classified into different categories as
follows:
1. Residential Buildings:
2. Educational Buildings:
3. Institutional Buildings:
4. Assembly Buildings:
5. Business Buildings:
6. Mercantile Buildings:
7. Industrial Buildings:
8. Storage Buildings:

4. Residential Building
Residential building means a private building. A residential building is one that is planned and in
like manner worked for occupants to live.

5. Educational Building
Educational building means a building exclusively used for a school, college or University,
recognized by the appropriate Board/ University/Council .

6. Any building or a part of building which are constructed by government, semi-government
organizations or any registered trusts used for purposes like medical or other treatment,
physical or mental illness institutes, auditoriums, children hospitals, old age homes, etc. are
included into the institutional buildings.
Institutional Building

7. Any building or a part of a building like theaters, assembly halls, auditorium, museums, exhibition
halls, club houses, dance halls, sports stadiums, transportation service such as bus stops, railway
stations, airports, taxi stands, etc. where groups of people gather for entertainment, travel, religious
purpose, programs or other similar works.
Assembly Building

8. Business Building
Any building or a part of building which is used for business purpose and used for transaction of
business, work or accounts for purposes like shops, beauty salons, barber shops, banks, launch
counters, food courts, breakfast stalls, professional corporate offices

9. These shall include buildings used for shop, markets, stores, wholesale or retail.
Mercantile Buildings

10. Industrial Buildings
These types of building are mainly used for manufacturing purposes. Here products or materials of
all kinds and properties are fabricated, assembled, or processed, for example, gas plants,
refineries, mills, dairies, etc.

11. StorageBuildings
These buildings are generally used for the storage or sheltering of goods, wares, or merchandise
like warehouses, cold storages, garages, stables, transit sheds, etc.

12. Hazardous Buildings
This building is used to store, handle, or manufacture highly corrosive, toxic, acid or other
liquids or chemicals that produce flame, fumes explosives, etc.

13. Classification Based On Structure
• Load bearing Structure
• Framed structure
• Load Bearing Structures: In this type of structures loads from roof slab or
trusses and floors are transmitted through walls to the firm soil below the
ground .This type of structures are available at elements like beams,
slabs rests directly on walls.

15. • Framed Structures: Reinforced cement concrete structures are the most
common type of construction today. They consist of a skeletonof beams &
columns. The load is transferred from beams to the columns and column intern
transfer the load directly to the sub soil through footing. Framed structures
are suitable for multi-storey building subjected to variety of extreme loads like
compressive, tensile torsion, shear along with moment.
• The open spaces in the skeleton are to be filled with brick walls or glass
panels.
Framed Structures

17. Part 2: Elements of Building
Construction

18. Common Building Components
Basic
Building
Components
Super
Structure
Substructure

19. Super Structure
• The superstructure is that part of the building which is
above the ground and which serves the purpose of
building’s intended use.
• It includes:
• Plinth level, Sill level and Lintel level
• Wall , Slab, columns and Beams
• Floors and Roofs
• Parapet
• Steps and stairs

20. Substructure
• The substructure is the lower portion of the
building, which is located below ground level
which transmits the load of the superstructure
to the sub soil.it includes
• Foundations

21. Foundation
• The basic function of foundation
• Transmit the load from building to the subsoil, in such a way
that
i. settlement are within permissible limit
ii. the soil does not fail in shear
iii. Reduce the load intensity
iv. Even distribution of load
v. Provide level surface

22. Types Of Foundation
• Foundations may be broadly classified as
• (a) Shallow Foundation
• (b) Deep foundation
• (a) Shallow Foundation
 Spread footing
 Combined footing
 Grillage Foundation
 Mat Foundation or Raft Foundation

23. Spread Footings

24. Combined Footing

25. Grillage Foundation

26. Mat/Raft Foundation

27. Deep Foundation
• Deep foundation may be of following types
i. Pile foundation
ii. Pier
iii. Well or caissons

28. Pile Foundation:- Pile Foundation is that
type of foundation in which the loads are
taken to a low level by means of vertical
members which may be timber

29. Pier Foundation: A Pier foundation
consist of cylindrical column of large
diameter to support and transfer large
superimposed load to the firm strata below.

30. Well Foundation

31. Super Structure:
The superstructure is that part of the
building which is constructed above the
plinth level.

32. Plinth level, Sill level and Lintel
level
• Plinth level means the level of
the floor of a building
immediately above the
surrounding ground.
• This level between the base
portion of the window and
portion of the floor above
ground level (upwards) is
called the Sill level. A mortar
bed or concrete bed is laid at the
base of the window.
• The level between the top
portion of the window and the
top slab is called the Lintel
level.

33. Wall
Wall is a structure defining an exact area and providing safety & shelter.
There are various types of walls used in the construction of buildings given
below. The construction of walls depending upon the types of material.
According to material, these are mainly classified as:
1. Brick masonry,
2. Stone masonry,
These are used to transfer the load from the roof to plinth beam. These are
also providing support to the building in some cases.

34. Walls

35. Columns are vertical members along which
beams and slab /roof is supported. They are
square, rectangular and circular in shape.
Columns

36. Beam
A beam is a horizontal structural member in a building to resist the lateral
loads applied to the beam’s axis.

37. Roof/ Slab
Roof: The upper most part of the building constitutes the roof. The Slab and
roof encloses the space and offers protection from rain, heat, snow, wind,
sound, fire

38. Floor: A floor is a plane area to support occupants, furniture's, and equipment.
Floor

39. Doors And Windows
• A door provides a connecting link between rooms, allowing easy free movement in
the building. Window are opening provided in walls.
• Doors and windows provide lighting and ventilation. The provide resistance to
weather, sound and heat. They provide security and privacy

40. Sizes of Doors
• For ResidentialArea
• Internal doors 0.9 x 2.0 m
• External doors 1.2 x 2 m
• Door for bath and w.c. 0.75 x 2.0 m

the building.
recommended to provide them with lending.
• Generally for residential building width of stair
is 1.0 m and 1.2 m
