Type 1 construction
What is type 1 construction?
What is fire resistive
What is type 2 construction?
What is non combustible
What is type 3 construction?
What is ordinary
What is type 4 construction?
What is heavy timber
What is type 5 construction?
What is wood frame
What are some commonly found fire resistive buildings?
What are schools, hospitals, high rise buildings
This type of construction is ordinarily composed of what?
What is unprotected metal structural components
The fire resistance requirements for interior construction of type 3 buildings are very what?
What is Little/limited as most interior components are completely made of wood
What are some buildings where you would find this type of construction?
What is mill factories, barns, churches, new and renovated office spaces, etc.
This type of construction is most what?
What is common of all building construction types
Type 1 buildings typically use reinforced concrete and ______________ construction?
Steel-frame
Unprotected metal components make this construction type prone to what?
What is early collapse
Exterior walls and structural members are constructed of?
What is usually non combustible materials
What is the main difference between the wood used in type 4 construction over the wood used in type 3 construction?
What is the wood in type 4 construction is much heavier than wood used in type 3 construction. It is more difficult to ignite and will withstand a fire for much longer.
What is a major weakness for this type construction?
What is void spaces are common, and in balloon-frame can be extensive.
What are often used to protect structural steel in type 1 construction?
What is Spray-on fireproofing materials
Do the structural elements of this type construction protect from fire conditions?
The structural elements rarely receive fire protection and are exposed to the heat of a fire.
What may exist in these buildings allowing for fire spread?
What are common cocklofts or attics
Type 4 construction usually consists of timbers of what size?
What is 6x6, 8x8 or larger
Is todays dimensional lumber used in this type construction actually what we think it is?
What is no today’s dimensional lumber is often smaller in size when compared to its legacy equivalent. Back then, a 2×4 was actually two inches by four inches. Some of today’s lumber is planed down to slightly smaller dimensions.
Even though these are the strongest built buildings under extreme fire conditions a type 1 building can what?
What is collapse
At what temperature does steel start to expand and begin to fail?
What is 800 degrees
What types of buildings would you possibly see with this type construction?
What are commercial strip malls, older schools, mercantile, business, buildings on our square...
One of the main advantages of this type construction is?
What is if its built to code it will have no void spaces or concealed spaces. Which in return helps reduce the horizontal and vertical spread of fire.
What is essential when it comes to this type construction?
What is smoke detectors!!! These type structures are a campfire waiting to happen.
