GENERAL APPLICATION NOTES - CONTINUED 27. Project Engineer of Record to determine minimum required spacing from ceiling support wires to un-braced suspended utilities. 28. Post installed anchor strength values used for attachment of seismic bracing to concrete decks are based on combined tension and shear in accordance with the recommendations of the Manufacturer's data given in the ICC evaluation report for the anchor. Refer to anchor installation pages for anchor torque, minimum anchor spacing and edge distance requirements. 29. Post installed mechanical expansion anchor embedment shown on ISAT details is to be measured before the anchor setting torque is applied. The observed anchor projection after the proper torque is applied may increase by a maximum of one bolt diameter. 30. Seismic bracing may not pass through a structural seismic separation joint. Utility systems that pass through a seismic separation joint must be seismically restrained within 5 feet of both sides of the separation or within 5 feet of point of connection of any hardware designed to accommodate seismic movement across the span of the separation joint. 31. With the approval of the Engineer of Record, utility systems within a basement that are suspended from the overhead deck may be braced to load bearing basement walls provided that the walls and the overhead deck will respond similarly during a seismic event. 32. A brace arm for a smaller distributed utility is not to be utilized as a transverse or longitudinal brace for an adjoining run of a larger distributed utility. 33. The ISAT component design and published loads to the structure are working loads. Maximum anchorage design loads are working loads based on combined tension and shear. Anchor ultimate strength values have been converted to working loads in accordance with the anchor manufacturer's ICC Report. 34. For ISAT seismic restraint components, refer to Section F. For all general components refer to Section H, Approved Hardware and Qualified Manufacturers. 35. Where the Code allows seismic restraints to be omitted from a component, provisions shall be made to avoid seismic impact with other components or impact with elements of the building structure. Impact risk analysis of non-braced components to be by others. 36. For anchorage designs presented in this Manual, light weight concrete is to be sand light weight concrete. 117q7 International Seismic Application Technology 14848 Northam Street,La Mirada, CA 90638 877-999-4728 (Toll Free) 714-523-0845(fax) www.isatsb.com Rev. 1 10/01/14 S alio >`T Page �9 f'9UCT�PQa< 4.4 •OF CAO 2012/15 IBC
