Every building and every portion thereof, except Type IV and V buildings and all one story buildings v &ieh are lees than twenty (20) feet in height shall be designed and contracted with bracing to resist the stresses pro- duced by lateral forces as provided in this Section. The stresses shall be calculated as the effects of a force applied horizontally at each floor or roof level above the foundation, such force to be proportional to the total dead plus live load of the building above any given plane and shall be considered as concentrated at sash floor or roof level. Where the design live load specified in Section 2304 for a particular building or portion thereof is fifty (50) pounds per square foot or less, such live load may be disregarded in tit's computation of the lateral forces re- quired by this Secti on. The full value or all live load s specified in Section 2304 more than fifty (50) pounds per square foot shall be used in such computation. The force shall be assumed to come from a direction at right angles to any elevation of the building. All bracing systems shall be located symmetrically about the center of mass of the buiMing ani shall be of sufficient extent and detail to safely move the whole mass of the building. No system can be used vdhich provides only for a small assumed movement of the foundation, or for only a small assumed amplitude of vibration or movement. The stresses to be provided for must be those which would be produced if the stricture were subject to an unlimited translation under the shear specified in paragraphs one and two of this Section. The factors to be employed to fix the lateral force shall vary with the character of the f oundati on 2- material and shall be as follows: 1. When the foundation rests upon material upon Which a load of two (2) or more tons per square f Oct is allowed, the horizontal force to be applied at any plane shall be assumed as seven and one -half per cent (7 1/2 %) of the total dead load plus the live load of the building above that plane. 2. When the foundation rests upon material upon ...a _ which a load of less than two (2) tons per square foot is allowed, the horizontal force to be applied at any plane shall be as sums d as ten per cent (10 %) of the total dead load plus the live load of the building above that plane. All buildings on pile foundations shall be included in this class. Where the design of a Type I or II building includes isolated footings, such footings shall be oom- pYetely interoonnected in two directions approximately at right angles to each other. Each such interconneoting member shall be capable of transmitting either by tension 1259 or compression the above seven and one half per cent (7 1/2 f) or ten per cent (10 f) of vertical load of the heavier only of the two footings it connects. The minimum gross size of each such member shall be twelve inches by twelve inches (12" x 12 ") and shall be reinforced with not less than the minimum reinforcement specified in Section 2621. With each set of plans filed, a brief statement of the following items shall be included: (a) A summation of the dead and live load of the building; floor by floor; which was used in figuring the shears for ihich t ha building is designed. 3- I:< 6O (b) A brief desoription of the bracing system used; the manner in which the designer expects sash system to act, and a. clear statement of any assumptions used, Assumption as to location of all points of counter- flexure in members must be stated. (c) Sample calculation of a typioal bent. Stresses in structural steel due to earthquake forces combined with other forces shall not exceed by more than fifty per cent (50 %) the allowable working stresses specified in Section 2702 and 2710, except that rivets may be stressed to fourteen thousand (14,000) pounds per square inch in tension. Tension and /or shear in briok walls and piers shall not exceed forty (40) pounds per square inch of net cross sectional area. The allowable unit shear in reinforced concrete walls eight (8) inches or more in . thickness shall not exceed four hundredths (o.04) of the ultimate compressive strength of the concrete. Stresses in all other materials shall not exceed by more than thirty - three and one -third per cent (33 1/3 %) the allowable working stresses permitted in this Code. (b) BOBD IM AND TYING. All buildings shall be firmly bonded and tied together as to their parts ant each one as a vf:ole in such manner that the structure will act as a unit. All veneer finish, cornices and ornamental details shall be bonded in the structure so as to form an integral part of it. This applies to the interior as well as to the exterior of the building. Bearing walls and other walls of unit masonry construction dhall be tied together at the level of each floor line from outside to outside of the structure by c ontinu- t 3 ous iron rods or other bonds of continuous strength and they 1 4- 1261 shall be tied to all vertical partition galls wherever practicable. -Nw (c) In the construction of all fire galls, towers, friezes, cornices; signs, overhanging or protrud- ing objeots, water towers, penthouses, eta., a factor of 100% against lateral forces shall be employed. (d) In view of events intervening between the original adoption of the Uniform Building Code, of nhieth this amendment is made a part and the date of the adoption of this amending ordinance, the use of lime mortar, as specified in Section 2409 of said Code, is hereby prohibited."
