20.08.110 Smax =the maximum displacement story drift at Level x. The value of AX need not exceed 3.0. (Ord. 1869 § 2, 2002) 20.08.112 Section 1630.8.2.1 - Amended -General: Section 1630.8.2.1 of the California Building Standards Code 2001 Edition (24 CCR), and including by reference the Uniform Building Code, is amended to read as follows: 1630.8.2.1 General. Where any por- tion of the lateral-load-resisting system is discontinuous, such as for vertical irregularity Type 4 in Table 16-L or plan irregularity Type 4 in Table 16-M, columns, beams, trusses or slabs supporting such discontinu- ous systems shall have the design strength to resist the combination loads resulting from the special seis- mic load combinations of Section 1612.4. The Connections of such discontinued elements to the support- ing members shall be adequate to transmit the forces for which the dis- continuous elements were required to be designed. EXCEPTIONS: 1. The quantity E,„ in Section 1612.4 need not exceed the maximum force that can be trans- ferred to the element by the lateral- force-resisting system. 2. Concrete slabs supporting light- frame wood shear wall systems or light-frame steel and wood structural panel shear wall systems. For Allowable Stress Design, the design strength may be determined using an allowable stress increase of 1.7 and a resistance factor, ~, of 1.0. This increase shall not be combined with the one-third stress increase permitted by Section 1612.3, but may be combined with the duration of load increase permitted in Chapter 23, Division III. (Ord. 1869 § 2, 2002) 20.08.115 Section 1630.10.2 - Amended -Calculated: Section 1630.10.2 of the California Building Standards Code 2001 Edition (24 CCR), and including by reference the Uniform Building Code, is amended to read as follows: 1630.10.2 Calculated. Calculated story drift using DM shall not exceed 0.025 times the story height for structures having a fundamental period of less than 0.5 second. For structures having a fundamental period of 0.5 second or greater, the calculated story drift shall not exceed 0.020/T ti3 times the story height. EXCEPTIONS: 1. These drift limits may be exceeded when it is demon- strated that greater drift can be toler- ated by both structural elements and nonstructural elements that could affect life safety. The drift used in this assessment shall be based upon the Maximum Inelastic Response Displacement, DM. 2. There shall be no drift limit in (Pleasanton April 2003) 704-16
