Fire-Resistive Construction

Back 4

Another term for Type I construction; construction that maintains its structural integrity during a fire.

Front 5

Fire Wall

Back 5

Fire-rated wall with a specified degree of fire resistance, built of fire-resistive materials and usually extending from the foundation up to and through the roof of a building, that is designed to limit the spread of a fire within a structure or between adjacent structures.

Heavy Fire Loading

Back 9

Presence of large amounts of combustible materials in an area or a building.

Lightweight Steel Truss

Back 10

Structural support made from a long steel bar that is bent at a 90-degree angle with flat or angular pieces welded to the top and bottom.

Front 11

Lightweight Wood Truss

Back 11

Structural supports constructed of 2- x 3-inch or 2- x 4-inch (50 mm by 75 mm or 50 mm by 100 mm) members that are connected by gusset plates.

Another term for Type II construction; construction made of the same materials as fire-resistive construction except that the structural components lack the insulation or other protection of Type I construction.

Front 15

Nonload-Bearing Wall

Back 15

Wall, usually interior, that supports only its own weight.

Front 16

Ordinary Construction

Back 16

Another term for Type III construction; construction that requires that exterior walls and structural members be made of noncombustible or limited combustible materials.

Veneer Walls

Back 22

Walls with a surface layer of attractive material laid over a base of common material.

Front 23
