Type 4: heavy timber
Type 5: wood frame
Structural members are of non-combustible materials that meet or exceed requirements prescribed by the applicable code
Fire restrictive construction
The strength of steel makes it a common material in fire resistive building. Steel is also a ready conductor of heat and must be protected by?
One of these
1. Encasement
2. Sprayed on protection
3. Membrane protection
____ absorbs the heat of a fire and retains the heat
Concrete
Employs materials that do not contribute to the development or spread of fire
Non combustible / Limited combustible construction
Steel fails commonly set at ____
1100 F
Constructed of wood, with exterior masonry wall
Ordinary construction
(Used for offices, retail sales, commercial occupancies, mixed occupancies and dwelling units
The space under a roof in a peaked building is called a _____ ; in a flat roofed building, it is referred to as a ____
Attic
Cockloft
Used wooden timbers of large dimension lumbar. Provides an excellent degree of fire resistance. Also called mill buildings
Heavy timber construction
_____ buildings present a tremendous fire problem due to the contents, methods of storage, and large amount of exposed wood. Once ignited they generate massive amounts of heat.
Mill buildings
Wood frame building in which all members are wooden or of similar material
Frame building construction
(Used for dwellings and commercial buildings)
The most common type of new frame construction is
Platform frame
Type of construction popular for churches, skating rinks, and buildings requiring a large clear span with no center support. These structures provide a massive fire load
Plank and beam frame construction
The ____ of the structure is the most important factor in determining whether a building will fail under fire conditions
Roof
If we are unable to push forward into a building, it indicates _____ and ___
