Answer:

Lightweight wood truss

Question 2: What are the five construction classifications?

Answer:

Type I fire resistive, type II noncombustible, type III ordinary, type IV heavy timber, type V wood frame Question 3: What is the primary material used for structural support in the construction of large modern buildings

Answer:

steel Question 4: This is the term to descry the second roof constructed over an older roof.

Answer:

A rain roof

Question 5: While reinforced concrete does perform well under fire conditions it can lose its strength through what process?

Answer:

Spalling

Question 6: what is the primary fire hazard with fire resistive construction?

Answer:

the contents and interior finishes

Question 7: noncombustible construction consist of what products?

Answer:

fire-resistance rating on all parts of the structure, can be all metal buildings, materials with no fire-resistance rating may only be used in limited quantities.

Question 8: What is the most common building material used in North America

Answer:

Wood

Question 9: This type of force is typically applied to the top chord of a truss

Answer:

compression Question 10: These types of trusses may be found in structures with rounded or arched roofs

Answer:

bowstring trusses

Question 11: Applying water to burning wood minimize damage by stopping what?

Answer:

The charring process Question 12: What building material is often used to insulate steel and wood structural members from potential fire conditions?

Answer:

Gypsum

Question 13: What are the most prominent building codes now in use?

Answer:

International codes council (ICC), NFPA 5000, Building construction and safety code (published by NFPA) Question 14: What is the primary fire concern specific to ordinary construction and what can be done to minimize this risk?

Answer:

Fire and smoke spreading through concealed spaces, fire blocking.Question 15: Firefighters should not be allowed to enter or go into the roofs of buildings that incorporate trusses in their construction if the buildings have been exposed to fire conditions for how long?

Answer:

5-10 minutes Question 16: Unprotected lightweight steel and wooden trusses can fail after how long?

Answer:

5-10 minutes Question 17: Failure of steel structural members can be anticipated at temperatures near or above?

Answer:

1000º F

Question 18: What is a description of fire resistive construction?

Answer:

construction that maintains it's structural integrity during a fire and is intended to allow occupants time to exit the building.Question 19: What are primary concerns that firefighters may have with cast iron?

Answer:

It may crack or shatter when rapidly cooled with water and bolts/connections that hold the cast iron to the building can fail causing large heavy sections of metal to come crashing down.

Question 20: What is the NFPA section that describes the five construction classifications?

Answer:

NFPA 220, Standard on types of building construction.

Question 21: Masonry consists of what type of materials?

Answer:

bricks, blocks, stones and unreinforced and reinforced concrete products Question 22: A 50' section of steel may elongate how much and at what temperature?

Answer:

4", 1000º F

Question 23: What are the strengths of noncombustible construction?

Answer:

confines fire well, almost as resistive to fire and type 1, almost as structurally stable as type 1, easier to ventilate than type 1

Question 24: fire resistive construction consists of what products?

Answer:

Mainly reinforced concrete with structural members that are protected by blown on insulation or automatic sprinklers.

Question 25: What is a description of noncombustible construction

Answer:

same materials as fire-resistive construction except that the structural components lack the insulation or other protection of type I construction.Question 26: Exterior walls and structural members are made of noncombustible or limited combustible materials (concrete blocks) and interior structural members are completely or partially of wood.

Answer:

Type III ordinary construction
