L = Live Load per unit area supported by the member. For storage live loads exceeding 500 kilograms per square meter (100 pounds per square foot), no reduction shall be made except that design live loads on columns may be reduced 20 percent. This live load reduction shall not exceed 40 per cent in garage for the storage of private pleasure cars having a capacity of not more than nine passengers per vehicle. Section 1.07: Deflection The deflection of any structural member shall not exceed the values set forth in Table No. 1.07-A, based upon the factors set forth in Table No. 1.07-B. The deflection criteria representing the most restrictive condition shall apply. Deflection criteria for materials not specified shall be developed in a manner consistent with the provisions of this Section. See Section 1.05 (d) for camber requirements. TABLE 1.07 - A MAXIMUM ALLOWABLE DEFLECTION FOR STRUCTURAL MEMBERS ¹ MEMBER LOADED MEMBER LOADED TYPE OF MEMBER WITH L.L. ONLY WITH L.L. + D.L. Roof Member Supporting Plaster or Floor Member L/360 L/240 ¹ Sufficient slope or camber shall be provided for flat roofs in accordance with Section 1.05 (d). L.L. D.L.

The occupant of the building shall be responsible for keeping the actual load below the allowable limits. Section 1.09: Retaining Walls Retaining walls shall be designed to resist the lateral pressure in accordance with accepted engineering practice. Walls retaining drained earth may be designed for pressure equivalent to that exerted by a fluid weighing not less than 30 pounds per cubic foot and having a depth equal to that of the retained earth. Any surcharge shall be in addition to the equivalent fluid pressure. Section 1.11: Walls and Structural Framing (a) General. Walls and structural framing shall be erected true and plumb in accordance with the design. Bracing shall be placed during rection wherever necessary to take care of all loads to which the structure may be subjected.
