Section 137-11-03 - Construction of Grandstands and Stadiums
Grandstands and stadiums shall be erected upon and attached to concrete or masonry foundations extended below the maximum depth of frost in the area where the structure is located and at least 6 inches above natural grade. They shall be designed to support, in addition to their own weight, a uniformly-distributed live load of not less than 100 pounds per square foot of gross horizontal projection of the grandstand. All seats and footboard members shall be designed for live loads of not less than 120 pounds per linear foot. They shall be designed to resist, without live load, a horizontal wind load of 30 pounds per square foot of all vertical projections of the structure, and with full live load, one-half of such wind load. They shall be designed to resist a horizontal swaying force applied to the seats in a direction parallel to the length of the seats, of 24 pounds per linear foot of seats, and in a direction perpendicular to the length of the seats of 10 pounds per linear foot of seats.
