Ch 2 Terms of Construction and Building Design

Question 1

Fire protection provided by automatic sprinklers and firefighters hose streams? Pg 13

Answer 1

Active Fire Protection

Question 2

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

Answer 2

Arch

Question 3

The three basic methods of constructing wood frame residential buildings are what? Pg 13

Answer 3

•Braced frame
•Platform
•Balloon frame

Question 4

A beam is a horizontal structural member, subject to compression, tension, and shear, supported by one of three methods? Pg 13

Answer 4

•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.

Question 5

It occurs when an exterior masonry wall drops like a falling curtain cut loose at the top? Pg 16

Answer 5

Curtain Fall Wall Collapse

Question 6

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

Answer 6

Inward/Outward Collapse

Question 7

A type of wood frame building collapse indicated by the burning structure slowly starting to tilt or lean over to one side? Pg 16

Answer 7

Lean Over Collapse

Question 8

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

Question 9

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

Answer 9

Ninety-Degree-Angle Wall Collapse

Question 10

The collapse of one floor section down upon the floor below in a flat, pancake like configuration? Pg 17

Answer 10

Pancake Floor Collapse

Question 11

The collapse of portions of burning taller structures on to smaller structures, causing the collapse of the smaller building? Pg 18

Answer 11

Secondary Collapse

Question 12
