<br />a. Elevated garage floors shall be capable of supporting a 2,000-pound load applied over a 20-square-inch area.
<br />b. Uninhabitable attics without storage are those where the maximum clear height between joists and rafters is less than 42
<br />inches, or where there are not two or more adjacent trusses with web configurations capable of accommodating an assumed
<br />rectangle 42 inches high by 24 inches in 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 load or a 300-pound concentrated load
<br />acting over an area of 4 square inches, whichever produces the greater stresses.
<br />d. A single concentrated load applied in any direction at any point along the top.
<br />e. See Section R502.2 for decks attached to exterior walls.
<br />f. Guard in -fill components (all those except the handrail), balusters and panel fillers shall be designed to withstand a
<br />horizontally applied normal load of 50 pounds on an area equal to 1 square foot. This load need not be assumed to act
<br />concurrently with any other live load requirement.
<br />g. Uninhabitable attics with limited storage are those where the maximum clear height between joists and rafters is 42
<br />inches or greater, or where there are two or more adjacent trusses with web configurations capable of accommodating an
<br />assumed rectangle 42 inches in height by 24 inches in 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 bottom chords where all of the following
<br />conditions are met:
<br />1. The attic area is accessible from an opening not less than 20 inches in width by 30 inches in length that is located
<br />where the clear height in the attic is a minimum of 30 inches.
<br />2. The slopes of the joists or truss bottom chords are no greater than 2 inches vertical to 12 units horizontal.
<br />3. Required insulation depth is less than the joist or truss bottom chord member depth.
<br />The remaining portions of the joists or truss bottom chords shall be designed for a uniformly distributed concurrent live
<br />load of not less than 10 lb/ft2.
<br />h. Glazing used in handrail assemblies and guards shall be designed with a safety factor of 4. The safety factor shall be
<br />applied to each of the concentrated loads applied to the top of the rail, and to the load on the in -fill components. These
<br />loads shall be determined independent of one another, and loads are assumed not to occur with any other live load.
