Chapter 10 Noncombustible Construction

Question 1

Aluminum

Answer 1

A lightweight metal that is both malleable and non-magnetic. This material has very good conductivity. This non-combustible material has a low melting point and a little mass per unit of area, so it disintegrates rapidly in fire.

Question 2

Angles

Answer 2

Steel members that have two legs at right angles to one another.

Question 3

Asphalt asbestos protected metal (AAPM)

Answer 3

Asphalt coating that is combustible and used as a weather protective coating on galvanized steel walls.

Question 4

Bar joist

Answer 4

A joist that generally runs in the same direction as a beam and forms a lightweight, long span system, used as floor supports and built up roofing supports.

Question 5

Bars

Answer 5

Plates fewer than 6 inches in width; may be square or round.

Question 6

Box column

Answer 6

A large hollow column built from steel plates.

Question 8

Bulbtee

Answer 8

A tee where the end of the cutoff is thickened.

Question 9

Bulkhead

Answer 9

An upright partition that divides a ship into compartments and is meant to prevent the spread of leakage or fire.

Question 10

Castellated beam

Answer 10
