1. The spacing of continuous ties shall not exceed 40 feet. Added chords of diaphragms may be used to form sub-diaphragms to transmit the anchorage forces to the main continuous crossties. 2. The maximum diaphragm shear used to determine the depth of the sub-diaphragm shall not exceed 75% of the maximum diaphragm shear. 1614.1.7 ASCE 7, Section 12.12.3. Replace ASCE 7 Section 12.12.3 as follows: 12.12.3 Minimum Building Separation. All structures shall be separated from adjoining structures. Separations shall allow for the maximum inelastic response displacement OM. OM shall be determined at critical locations with consideration for both translational and torsional displacements of the structure as follows: ~M = C d S max (Equation 16-45) M max Where i5 max is the calculated maximum displacement at Level x as define in ASCE 7 Section 12.8.4.3. Adjacent buildings on the same property shall be separated by at least a distance o m t, where 4 mT -I (om1 )2 + (gym 2 )2 ~1/2 (Equation 16-46) and Om 1 and Om2 are the maximum inelastic response displacements of the adjacent buildings. Where a structure adjoins a property line not common to a public way, the structure shall also be set back from the property line by at least the displacement, .M, of that structure. Exception: Smaller separations or property line setbacks shall be permitted when justified by rational analyses. 1614.1.8 ASCE 7, 12.12.4. Modify ASCE 7 Section 12.12.4 to read as follows: 12.12.4 Deformation Compatibility for Seismic Design Category D through F. For structures assigned to Seismic Design Category D, E, or F, every structural component not included in the seismic force-resisting system in the direction under consideration shall be designed to be adequate for the gravity load effects and the seismic forces resulting from displacement to the design story drift (^) as determined in accordance with Section 12.8.6 (see also Section 12.12.1). Exception: Reinforced concrete frame members not designed as part of the seismic force-resisting system shall comply with Section 21.9 of ACI 318. 56
