lateral loads imposed by the veneer. (3) Consideration shall be given to differential movements of the supports including those
caused by temperature changes, shrinkage, creep, and deflection.
(4) Adhered veneer and its backing shall be designed to have a bond to the supporting
elements sufficient to withstand shearing stresses due to their weights including seismic
effects on the total assemblage. (5) Anchored veneer and its backing shall designed t o have a bond to the supporting
sufficient to withstand shearing stresses due to their weights including
seismic effects on the total assemblage.
(6) Anchors supports and ties shall be non-combustible and corrosion-resistant.
SECTION 1204. Enclosure of Vertical Openings
(a) General. Vertical openings shall be enclosed depending upon the fire-resistive requirements
of a particular type of construction as set forth in this Code.
(b) Elevator Enclosures. Walls and partitions enclosing elevators and escalators shall be of not
less than the fire-resistive construction required under the types of Construction. Enclosing walls of elevator shafts may consist of wire glass set in metal frames on the entrance side only. Elevator shafts
extending through more than two storeys shall be equipped with and approved means of adequate
ventilation to and through the main roof of the building: Provided, that in those buildings housing

shall not be required for escalators: Provided, further that the top of the escalato opening at each storey
shall be provided with a draft curtain. Such draft curtain shall enclose the perimeter of the unenclosed
opening and shall extend from the ceiling downward at least 300 millimeters on all sides. Automatic
sprinklers shall be provided around the perimeter of the opening and within a 600 millimeters of the
