In accordance with Section R301.2.1.5, where there is local historical data documenting structural damage to buildings due to topographic <br /> wind speed -up effects, the jurisdiction shall fill in this part of the table with "YES." Otherwise, the jurisdiction shall indicate "NO" in this <br /> part of the table. <br /> 20.10.050 CRC Table R301.5 amended — Minimum Uniformly Distributed Live <br /> Loads <br /> Table R301.5 is amended to read as follows: <br /> TABLE R301.5 <br /> MINIMUM UNIFORMLY DISTRIBUTED LIVE LOADS <br /> (in pounds per square toot) <br /> USE LIVE LOAD <br /> Attics without storage' 10 <br /> Attics with limited storage" g 20 <br /> Habitable attics and attics served 30 <br /> with fixed stairs <br /> Balconies (exterior) and decks° 60 <br /> Fire esca es 40 <br /> Guardrails and handrails' 200h <br /> Guardrail in -fill components 50h <br /> Passen:er vehicle garagesa 50a <br /> Rooms other than sleeping room 40 <br /> Sleeiin: rooms 30 <br /> Stairs 40C <br /> For SI: 1 pound per square foot= 0.0479 kPa, 1 square inch = 645 mmz. I pound =4.45 N. <br /> a. Elevated garage floors shall be capable of supporting a 2,000 -pound load applied over a 20- square -inch area. <br /> b. Attics without storage are those where the maximum clear height between joist and rafter is less than 42 inches, or where there are not two or <br /> more adjacent trusses with the same web configuration capable of containing a rectangle 42 inches high by 2 feet wide, or greater, located within <br /> the plane of the truss. For attics without storage, this live load need not be 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 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 top. <br /> e. Decks that are not exterior balconies may be designed at 40 psj See Section R502.2.2 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 horizontally applied normal <br /> load of 50 pounds on an area equal to 1 square foot. This load need not be assumed to act concurrently with any other live load requirement. <br /> g. For attics with limited storage and constructed with trusses, this live load need be applied only to those portions of the bottom chord where <br /> there are two or more adjacent trusses with the same web configuration capable of containing a rectangle 42 inches high or greater by 2 feet wide <br /> or greater, located within the plane of the 'suss. The rectangle shall fit between the top of the bottom chord and the bottom of any other truss <br /> member, provided that each of the following criteria is met. <br /> 1. The attic area is accessible by a pull -down stairway or framed in accordance with Section R807.1. <br /> 2. The truss has a bottom chord pitch less than 2:12. <br /> 3. Required insulation depth is less than the bottom chord member depth. The bottom chords of trusses meeting the above criteria for <br /> limited storage shall be designed for the greater of the actual imposed dead load or 10 psf, uniformly distributed over the entire span. <br /> h. Glazing used in handrail assemblies and guards shall be designed with 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 -fill components. These loads shall be determined independent of one <br /> another, and loads are assumed not to occur with any other live load. <br /> 43 <br />
