Ch 2 Terms of Construction and Building Design Flashcards
Fire protection provided by automatic sprinklers and firefighters hose streams? Pg 13
Active Fire Protection
A curved masonry structure used as a support over an open space. The removal or destruction of any part of an arch will cause the entire arch to collapse? Pg 13
Arch
The three basic methods of constructing wood frame residential buildings are what? Pg 13
•Braced frame
•Platform
•Balloon frame
A beam is a horizontal structural member, subject to compression, tension, and shear, supported by one of three methods? Pg 13
•Cantilever Beam Support- a beam supported or anchored at only end, which is considered a collapse hazard during fire exposure. Of the types of beam supports, it has the least amount of structural stability during a fire.
•Continuous Beam Support- A beam supported at both ends and at the center. During a fire, it has the greatest structural stability of the three types beam supports.
•Simple Supported Beam- A beam supported at both ends. If the deflection at the center of such a beam becomes excessive, a collapse may occur. A simple supported beam is more stable under fire conditions than a cantilever beam but less stable than a continuous supported beam.
It occurs when an exterior masonry wall drops like a falling curtain cut loose at the top? Pg 16
Curtain Fall Wall Collapse
The collapse of an exterior wall that breaks apart horizontally. The top collapses inward, back on top of the structures; the bottom collapses outward on to the street? Pg 16
Inward/Outward Collapse
A type of wood frame building collapse indicated by the burning structure slowly starting to tilt or lean over to one side? Pg 16
Lean Over Collapse
A floor collapse in which one end of the floor beams remains partially supported by the bearing wall, and the other end of the floor beams collapses on to the floor below or collapses but remains unsupported? Pg 16
Lean To Floor Collapse
A type of burning building wall collapse. The wall falls straight out as a monolithic piece at a 90 degree angle, similar to a falling tree? Pg 16
Ninety-Degree-Angle Wall Collapse
The collapse of one floor section down upon the floor below in a flat, pancake like configuration? Pg 17
Pancake Floor Collapse
The collapse of portions of burning taller structures on to smaller structures, causing the collapse of the smaller building? Pg 18
Secondary Collapse
A floor collapse in the shape of a tent? Pg 18
Tent Floor Collapse
The collapse of a floor at the center of the floor beams? Pg 18
V Shape Floor Collapse
What is a bend, twist or curve of a structural element under a load? p. 21
Deflection
What is a wall reinforcement of a brace built on the outside of a structure, sometimes called a “wall column”? p. 15
Buttress
What is the term “kips” most often used in reference to? p. 24
Strength of steel
Which of the following is a parapet wall an example of? p. 33
Freestanding wall
Which type of collapse occurs when floor beams pull loose or collapse at both ends? p. 17
Pancake floor
At how many points is the cantilever beam supported? p. 13

What is a combination of dead load and live load? p. 22
Gravity load
What is used to attach the suspended ceiling to the beams? p. 31
Straps
Where on the structure is the spandrel wall located? p. 35
Between window openings
Which of the following is at the bottom of the hierarchy of building elements? p. 24
Deck
Which part of the firefighter will most likely NOT be burned when his/her foot falls through the deck? p. 21
Torso
How many flanking areas exist around a burning building? p. 21
Four
Where is a coping stone located? p. 20
On top of a parapet wall
At what angle will the nonbearing wall fall when the building is made of balloon construction? p. 13
90-degree
Which is wood that is larger than 2 X 4 inches (5 cm X 10cm)? p. 32
Timber
After what amount of fire exposure can the open-web steel bar joist fail?
p. 28
5 to 10 minutes
Which of the following items is the roof NOT designed to support? p. 30
Firefighters
Which type of load is an explosion an example of? p. 27
Impact
What is active fire protection provided by? p. 13
Automatic sprinklers
Which part of an arch can be removed or destroyed without causing it to collapse? p. 13
None of it can be removed
Which is in the correct support order?
p. 32
Trimmer beam, header beam, tail beam
What are the top and bottom of an I-beam called? p. 24
Flanges
Which has the greatest stability during fire conditions? p. 13
Continuous beam support
