International Building Code Section 714


International Building Code 714.1

Requirements. The fire-resistance rating of structural
members and assemblies shall comply with the requirements
for the type of construction and shall not be less than the rating
required for the fire-resistance-rated assemblies supported.
Exception: Fire barriers, fire partitions and smoke barriers
as provided in Sections 706.5, 708.4 and 709.4, respectively.

International Building Code 714.2

Protection of structural members. Protection of columns,
girders, trusses, beams, lintels or other structural members
that are required to have a fire-resistance rating shall
comply with this section.

Individual protection. Columns, girders, trusses,
beams, lintels or other structural members that are required
to have a fire-resistance rating and that support more than
two floors or one floor and roof, or support a load-bearing
wall or a nonload-bearing wall more than two stories high,
shall be individually protected on all sides for the full length
with materials having the required fire-resistance rating.
Other structural members required to have a fire-resistance
rating shall be protected by individual encasement, by a
membrane or ceiling protection as specified in Section 711,
or by a combination of both. Columns shall also comply
with Section 714.2.2.

Membrane protection. King studs and
boundary elements that are integral elements in
load-bearing walls of light-framed construction shall be
permitted to have required fire-resistance ratings provided
by the membrane protection provided for the
load-bearing wall.

Column protection above ceilings. Where columns
require a fire-resistance rating, the entire column,
including its connections to beams or girders, shall be protected.
Where the column extends through a ceiling, fire
resistance of the column shall be continuous from the top of
the foundation or floor/ceiling assembly below through the
ceiling space to the top of the column.

Truss protection. The required thickness and construction
of fire-resistance-rated assemblies enclosing
trusses shall be based on the results of full-scale tests or
combinations of tests on truss components or on approved
calculations based on such tests that satisfactorily demonstrate
that the assembly has the required fire resistance.

Attachments to structural members. The edges
of lugs, brackets, rivets and bolt heads attached to structural
members shall be permitted to extend to within 1 inch (25
mm) of the surface of the fire protection.

Reinforcing. Thickness of protection for concrete
or masonry reinforcement shall be measured to the outside
of the reinforcement except that stirrups and spiral reinforcement
ties are permitted to project not more than
0.5-inch (12.7 mm) into the protection.

International Building Code 714.2.1

Individual protection. Columns, girders, trusses,
beams, lintels or other structural members that are required
to have a fire-resistance rating and that support more than
two floors or one floor and roof, or support a load-bearing
wall or a nonload-bearing wall more than two stories high,
shall be individually protected on all sides for the full length
with materials having the required fire-resistance rating.
Other structural members required to have a fire-resistance
rating shall be protected by individual encasement, by a
membrane or ceiling protection as specified in Section 711,
or by a combination of both. Columns shall also comply
with Section 714.2.2.

Membrane protection. King studs and
boundary elements that are integral elements in
load-bearing walls of light-framed construction shall be
permitted to have required fire-resistance ratings provided
by the membrane protection provided for the
load-bearing wall.

International Building Code 714.2.1.1

Membrane protection. King studs and
boundary elements that are integral elements in
load-bearing walls of light-framed construction shall be
permitted to have required fire-resistance ratings provided
by the membrane protection provided for the
load-bearing wall.

International Building Code 714.2.2

Column protection above ceilings. Where columns
require a fire-resistance rating, the entire column,
including its connections to beams or girders, shall be protected.
Where the column extends through a ceiling, fire
resistance of the column shall be continuous from the top of
the foundation or floor/ceiling assembly below through the
ceiling space to the top of the column.

International Building Code 714.2.3

Truss protection. The required thickness and construction
of fire-resistance-rated assemblies enclosing
trusses shall be based on the results of full-scale tests or
combinations of tests on truss components or on approved
calculations based on such tests that satisfactorily demonstrate
that the assembly has the required fire resistance.

International Building Code 714.2.4

Attachments to structural members. The edges
of lugs, brackets, rivets and bolt heads attached to structural
members shall be permitted to extend to within 1 inch (25
mm) of the surface of the fire protection.

International Building Code 714.2.5

Reinforcing. Thickness of protection for concrete
or masonry reinforcement shall be measured to the outside
of the reinforcement except that stirrups and spiral reinforcement
ties are permitted to project not more than
0.5-inch (12.7 mm) into the protection.

International Building Code 714.3

Embedments and enclosures. Pipes, wires, conduits,
ducts or other service facilities shall not be embedded in the
required fire protective covering of a structural member that is
required to be individually encased.

International Building Code 714.4

Impact protection. Where the fire protective covering
of a structural member is subject to impact damage from moving
vehicles, the handling of merchandise or other activity, the
fire protective covering shall be protected by corner guards or
by a substantial jacket of metal or other noncombustible material
to a height adequate to provide full protection, but not less
than 5 feet (1524 mm) from the finished floor.

International Building Code 714.5

Exterior structural members. Load-bearing structural
members located within the exteriorwalls or on the outside of a
building or structure shall be provided with the highest
fire-resistance rating as determined in accordance with the following:
1. As required by Table 601 for the type of building element
based on the type of construction of the building;
2. As required by Table 601 for exterior bearing walls
based on the type of construction; and
3. As required by Table 602 for exterior walls based on the
fire separation distance.

International Building Code 714.6

Bottom flange protection. Fire protection is not
required at the bottom flange of lintels, shelf angles and plates,
spanning not more than 6 feet (1829 mm) whether part of the
structural frame or not, and from the bottom flange of lintels,
shelf angles and plates not part of the structural frame, regardless
of span.

International Building Code 714.7

Seismic isolation systems. Fire-resistance ratings for
the isolation system shall meet the fire-resistance rating
required for the columns, walls or other structural elements in
which the isolation system is installed in accordance with Table
601.
Isolation systems required to have a fire-resistance rating
shall be protected with approved materials or construction
assemblies designed to provide the same degree of fire resistance
as the structural element in which it is installed when
tested in accordance with ASTM E 119 (see Section 703.2).
Such isolation system protection applied to isolator units
shall be capable of retarding the transfer of heat to the isolator
unit in such a manner that the required gravity load-carrying
capacity of the isolator unit will not be impaired after exposure
to the standard time-temperature curve fire test prescribed in
ASTM E 119 for a duration not less than that required for the
fire-resistance rating of the structure element in which it is
installed.
Such isolation system protection applied to isolator units
shall be suitably designed and securely installed so as not to
dislodge, loosen, sustain damage or otherwise impair its ability
to accommodate the seismic movements for which the isolator
unit is designed and to maintain its integrity for the purpose of
providing the required fire-resistance protection.
