Interior walls, permanent partitions, and temporary partitions which exceed three-fourth of the height of the room in which they are placed shall be designed to resist all loads to which they are subjected but not less than a force of 10 pounds per square foot applied perpendicular to the walls. The deflection of such walls under a load of five pounds per square foot shall not exceed 1/240 of the span for wals with little finishes and 1/120 of the span for walls with flexible finishes. See Table No. 1.07-A for earthquake design requirements where such requirements are more restrictive. Section 1.12: Anchorage Concrete or masonry walls shall be anchored to all floors and roofs which provide lateral support for the wall or are required to provide stability for the wall. Such anchorage shall be capable of resisting the horizontal forces specified in this Chapter or a minimum force of 200 pounds per linear foot of wall, whichever is the larger. Required anchor in masonry walls of hollow units or cavity walls shall enter a reinforced grouted structural element of the wall. Section 1.13: Heliport and Helistop Landing Areas In addition to other design requirements of this Chapter, heliport and helistop landing or touchdown areas shall be designed for the maximum stress induced by the following: 1. Dead load plus actual weight of the helicopter. 2. Dead load plus a single concentrated impact load covering one square foot (1 sq. ft.) of .75 times the fully loaded weight of the helicopter if it is equipped with hydraulic type shock absorvers, or 1.5 times the fully loaded weight of the helicopter if it is equipped with a rigid or skid type landing gear. 3. The dead load plus a uniform live load of 100 pounds per square foot. The required live load may be reduced in accordance with the formula in Section 1.06. CHAPTER 2 LATERAL FORCES Section 2.01: Earthquake Forces (a) General. These lateral force requirements are intended to provide minimum standards as design criteria toward making buildings and other structures earthquake resistant. The provisions of this Section apply to the structures as a unit and also to all parts thereof, including the structural frame or walls, floor and roof systems, an other structural features. The provisions incorporated in this Section are general and, in specific cases, may be interpreted as to detail in order that the intent shll be fulfilled. Every building or structure and every portion thereof, except Types I and II buildings of Group A occupancy which are less than 7.5 meters (25 feet) in height, and minor accessory buildings, shall be designed and constructed to resist stresses produced by lateral forces as provided in this Section...
