TABLE 303.2
DESIGN LOADS
TIERED SEATING ELEMENT LOAD TYPE LOAD
Seats (vertical) L 120 pounds per linear foot.
Treads L Stair treads and stepped aisle treads shall be designed to resist a minimum concentrated load of 300 pounds on an area of 4 square inches.
Handrails and guards, uniform load Rr Handrail assemblies and guards shall be designed to resist a load of 50 pounds per linear foot (pound per foot) applied in any point at the top. The supporting elements shall transfer this load to the structure.
Handrails and guards, concentrated load Rr Handrail assemblies and guards shall be able to resist a single concentrated load of 200 pounds, applied in any direction at any direction along the top. Attachment devices and supporting elements shall transfer this load to the structure.
Guards, infill components Rr Intermediate rails (all those except the handrail), balusters, and panel fillers (including flexible infill components) shall be designed to withstand a horizontally applied normal load of 50 pounds on an area equal to 1 square foot, including openings and space between rails. Application of the loads shall not allow guard openings greater than that permitted by Sections 408.2 and 503.2.
For SI: 1 square inch = 645.46 mm2, 1 square foot = 0.0929 m2, 1 pound = 4.448 N, 1 pound per linear foot = 14.594 N/m.

Parallel and perpendicular sway loads need not be considered simultaneously. Also uniform, concentrated and infill loads need not be considered simultaneously. Partial loading shall be addressed to account for the full intensity of the appropriately reduced live load applied only to a portion of a structure or member if it produces a more unfavorable load effect than the same intensity applied over the full structure or member.
