SECTION 1607 LIVE LOADS
1607.7
Loads on handrails, guards, grab bars and vehicle barriers.
Handrails, guards, grab bars as designed in ICC A117.1 and
vehicle barriers shall be designed and constructed to the
structural loading conditions set forth in this section.
1607.7.1 Handrails and guards. Handrail assemblies and
guards shall be designed to resist a load of 50 plf (0.73
kN/m) applied in any direction at the top and to transfer
this load through the supports to the structure. Glass handrail
assemblies and guards shall also comply with Section
2407.
Exceptions:
1.
For one- and two-family dwellings, only the single concentrated
load required by Section 1607.7.1.1 shall be applied.
2.
In Group 1-3, F, Hand S occupancies, for areas that are
not accessible to the general public and that have an occupant
load less than 50, the minimum load shall be 20 pounds per
foot (0.29 kN/m) .
1607.7.1.1 Concentrated load. Handrail assemblies
and guards shall be able to resist a single concentrated
load of 200 pounds (0.89 kN), applied in any direction
at any point along the top, and have attachment devices
and supporting structure to transfer this loading to appropriate
structural elements of the building. This load need not
be assumed to act concurrently with the loads specified
in the preceding paragraph.
1607.7.1.2
Components. Intermediate rails (all those except the
handrail), balusters and panel fillers shall be designed
to withstand a horizontally applied normal load of 50
pounds (0.22 kN) on an area equal to 1 square foot (0.093m2),
including openings and space between rails. Reactions
due to this loading are not required to be superimposed
with those of Section 1607.7.1 or 1607.7.1.1.
1607.7.1.3
Stress increase. Where handrails and guards are designed
in accordance with the provisions for allowable stress
design (working stress design) exclusively for the loads
specified in Section 1607.7.1, the allowable stress for
the members and their attachments are permitted to be
increased by one-third.
1607.7.2
Grab bars, shower seats and dressing room bench seats.
Grab bars, shower seats and dressing room bench seat systems
shall be designed to resist a single concentrated load of
250 pounds (1.11 kN) applied in any direction at any point.
1607.7.3 Vehicle barriers.
Vehicle barrier systems for passenger cars shall be designed
to resist a single load of 6,000 pounds (26.70 kN) applied
horizontally in any direction to the barrier system and
shall have anchorage or attachment capable of transmitting
this load to the structure. For design of the system, the
load shall be assumed to act at a minimum height of 1 foot,
6 inches (457 mm) above the floor or ramp surface on an
area not to exceed 1 square foot (305 mm2), and
is not required to be assumed to act concurrently with any
handball or guard loadings specified in the preceding paragraphs
of Section 1607.7.1. Garages accommodating trucks and buses
shall be designed in accordance with an approved method
that contains provision for traffic railings.
