Buildings are classified based on occupancy and type of construction. There are 10 types of occupancies including residential, commercial, educational, and industrial. Buildings are also classified into 5 types of construction based on fire resistance: (1) fire resistive, (2) non-combustible, (3) ordinary, (4) heavy timber, and (5) wood framed. Each construction type has different fire resistance specifications for elements like exterior walls, structural frames, floors/ceilings, and roofs. The classification system considers factors like building height, materials used, and fire protection to determine a structure's resistance to fire over time.

13. Classification Of buildings
based on
Type of construction

14. Based on the type of construction, buildings are classified into 5
categories.
1) Fire resistive Buildings (Type 1A , 1B)
2) Non–Combustible Buildings (Type 2A, 2B)
3) Ordinary Buildings (Type 3A, 3B)
4) Heavy timber Buildings (Type 4)
5) Wood framed Buildings (Type 5A, 5B)

15. 1)Fire resistive buildings: (Type 1A, 1B)
• These type of buildings are generally high raised, and the stoutest of all, which are
usually of more than 69 feet tall.
• They are constructed of concrete and protected steel, (coated with fire resistant
material) which are designed to hold fire.
• This type of buildings are generally residential and industrial buildings.
• The fire resistance is valid only for a specific time, depending up on the type of
construction. Let us have a look at the resistive time for Industrial and Residential
buildings.

16. Industrial buildings:
• *3 Hr- Exterior Walls.
• *3 Hr- Structural Frame.
• *2 Hr-Floor/Ceiling assembly.
• *1 ½ Hr-Roof Protection.
Residential buildings:
• *2 Hr- Exterior Walls.
• *2 Hr-Structural frame.
• *2 Hr-Ceiling/Floor Separation.
• *1 Hr-Ceiling/Roof assembly.
It means that according to the time given above, the building is resistant towards fire,
and after the specified time it must be super viewed by the fire control authorities.

17. 2)Non- combustible buildings:( Type 2A,2B)
• These buildings are generally the new buildings and remodels of commercial
structures.
• The walls and roofs are constructed of non- combustible materials.(i.e. walls are rein
forced masonry and the roofs have metal structural members) .
• The top of the roofs are covered with light weight concrete etc.
Protected Non-combustible.(common in school buildings)
 *1 Hr-Exterior Walls
 *1 Hr-Structural Frame
 *1 Hr-Floor/Ceiling/Roof Protection
Unprotected Non-combustible.(common in commercial buildings):
 These Buildings are constructed of noncombustible materials but these
materials have no fire resistance.

18. 3)Ordinary buildings:(Type 3A,3B)
 These buildings may be of old or newer constructions. They have non-combustible
walls and wooden roof.
 Older constructions may have un rein-forced masonry and have conventionally framed
roof, while newer houses have light weight roof systems, supported by R.C.C masonry
or tilt slab.
 The walls and the roofs are 1 hour fire protected.
 Ordinary buildings are of the other type also, which is unprotected combustible. walls
are of a wooden roof and the floor assembly is not protected against fire.
 These buildings are frequently found in "warehouse“, districts of older cities.
Specifications:
 *2 Hr. Exterior Walls
 *No fire resistance for structural frame, floors, ceilings, or roofs.

19. 4) Heavy Timber :
 These buildings were most commonly built before 1960, when bolts and metal plates
were used as connectors.
 It utilizes large dimensional lumber for structural members and interior elements. These
buildings hold up well under fire conditions.
 It is critical that, as these buildings are often poorly maintained, or have termites, the
weathering issues contributes an earlier-than-expected collapse.
 To qualify the structure, all wooden members must have a minimum nominal dimension
of 8 inches.
Specifications:
 *2 Hr. Exterior Walls
 *1 Hr. Structural Frame or Heavy Timber (Heavy Timber Floor/Ceiling/Roof Assemblies)

20. 5)Wood framed buildings: (Type 5A,5B)
 This type of construction is found in many modern homes. The walls and roofs are
made of combustible materials—most commonly wood.
 It has a few negative characteristics:
 It is not highly fireproof, as it is made of wood.
 It is not strong enough to resist major wind events such as tornadoes and
hurricanes.
Protected Wood Frame:
 It is Commonly used in the construction of newer apartment buildings; there is no
exposed wood visible.
 1 Hr. Exterior Walls
 1 Hr. Structural Frame
 1 Hr. Floor/Ceiling/Roof
Unprotected Wood Frame:
It is used commonly at single family homes and garages. They often have exposed wood
so there is no fire resistance.
