<br />For SI: 1 pound per square foot = 0.0479 kPa, 1 square inch = 645 mm2, 1
<br />pound = 4.45 N.
<br />a. Elevated garage floors shall be capable of supporting a 2,000-pound
<br />load applied over a 20-square-inch area.
<br />b. Uninhabitable attics without storage are those where the clear height
<br />between joists and rafters is not more than 42 inches, or where there are
<br />not two or more adjacent trusses with web configurations capable of
<br />accommodating an assumed rectangle 42 inches in height by 24 inches in
<br />width, or greater, within the plane of the trusses. This live load need not be
<br />assumed to act concurrently with any other live load requirements.
<br />c. Individual stair treads shall be designed for the uniformly distributed live
<br />load or a 300-pound concentrated load acting over an area of 4 square
<br />inches, whichever produces the greater stresses.
<br />d. A single concentrated load applied in any direction at any point along the
<br />top.
<br />e. See Section R507.1 for decks attached to exterior walls.
<br />f. Guard in -fill components (all those except the handrail), balusters and
<br />panel fillers shall be designed to withstand a horizontally applied normal
<br />load of 50 pounds on an area equal to 1 square foot. This load need not be
<br />assumed to act concurrently with any other live load requirement.
<br />g. Uninhabitable attics with limited storage are those where the clear
<br />height between joists and rafters is not greater than 42 inches, or where
<br />there are two or more adjacent trusses with web configurations capable of
<br />accommodating an assumed rectangle 42 inches in height by 24 inches in
<br />width, or greater, within the plane of the trusses.
<br />The live load need only be applied to those portions of the joists or truss
<br />bottom chords where all of the following conditions are met:
<br />1.The attic area is accessible from an opening not less than 20
<br />inches in width by 30 inches in length that is located where the clear
<br />height in the attic is not less than 30 inches.
<br />2.The slopes of the joists or truss bottom chords are not greater than
<br />2 inches vertical to 12 units horizontal.
<br />3.Required insulation depth is less than the joist or truss bottom
<br />chord member depth.
<br />The remaining portions of the joists or truss bottom chords shall be
<br />&signed for a uniformly distributed concurrent live load of not less than 10
<br />pounds per square foot.
<br />h. Glazing used in handrail assemblies and guards shall be designed with
<br />a safety factor of 4. The safety factor shall be applied to each of the
<br />concentrated loads applied to the top of the rail, and to the load on the in -
<br />fill components. These loads shall be determined independent of one
<br />another, and loads are assumed not to occur with any other live load.
