Where other factored load combinations are specifically required by the provisions of this <br />code. <br />Section 7-5-190: DETAILING REQUIREMENTS IN SEISMIC ZONES 3 AND 4. <br />Section 1630.8.2.2 of the Code is deleted and replaced with the following: <br />1630.8.2.2 Detailing Requirements in Seismic Zones 3 and 4. In Seismic Zones 3 and 4, elements <br />supporting discontinuous systems shall meet the following detailing or member limitations: <br />1. Reinforced concrete or reinforced masonry elements designed primarily as axial -load <br />members shall comply with Section 1921.4.4.5. <br />2. Reinforced concrete elements designed primarily as flexural members and supporting <br />other than light -frame wood shear wall systems or light -frame steel and wood <br />structural panel shear wall systems shall comply with Sections 1921.3.2 and <br />1921.3.3. Strength computations for portions of slabs designed as supporting <br />elements shall include only those portions of the slab that comply with the <br />requirements of these Sections. <br />3. Masonry elements designed primarily as axial -load -carrying members shall comply <br />with Sections 2106.1.12.4, Item 1, and 2108.2.6.2.6. <br />4. Masonry elements designed primarily as flexural members shall comply with Section <br />2108.2.6.2.5. <br />5. Steel elements designed primarily as flexural members or trusses shall have bracing <br />for both top and bottom beam flanges or chords at the location of the support of the <br />discontinuous system and shall comply with the requirements of AISC-Seismic Part <br />I, Section 9.4b. <br />Wood elements designed primarily as flexural members shall be provided with lateral bracing or <br />solid blocking at each end of the element and at the connection location(s) of the discontinuous <br />system. <br />Section 7-5-191: STORY DRIFT CALCULATION. Section 1630.10.2 of the Code is <br />deleted and replaced with the following: <br />1630.10.2 Calculated. Calculated story drift using A shall not exceed 0.025 times the story <br />height for structures having a fundamental period of less than 0.5 second. For structures having a <br />fundamental period of 0.5 second or greater, the calculated story drift shall not exceed 0.020/T 1/3 <br />times the story height. <br />EXCEPTIONS: <br />1. These drift limits may be exceeded when it is demonstrated that greater drift can be <br />tolerated by both structural elements and nonstructural elements that could affect life <br />safety. The drift used in this assessment shall be based upon the Maximum Inelastic <br />
