Splayed Seismic Bracing Wire • The intent of the code is not to use lay -in acoustical ceiling grid as an alternate method of bracing interior non -load bearing walls, unless the ceiling system has been designed (engineered) to support the partition. • It is accepted industry practice to attach the partition track to the acoustical grid system temporarily for alignment until D permanent bracing is installed. The attachment of stud track to the acoustical grid does not violate the intent of the code, provided that the permanent bracing options for the nonbearing Structural ] Structural partitions are installed (reference ICBO ES report 4071 Concrete Steel Seismic Connection Details for Gypsum Nonbearing Partitions and Suspended Ceilings).

Splayed Seismic Bracing Wire NOTE: • A non -load bearing partition (gypsum board or plaster) that ends at or just above a suspended lay -in -tile ceiling system requires lateral support by means directly to the structure. Exceptions: © • if the partition goes all the way up and is attached directly to the structure. Illr • if end of partition is within 8 feet (2,500mm) of an Wood —' intersecting partition. • A partition system may be attached directly to the support and/or framing member of a suspended gypsum board or plaster system, 12 inches (300 mm) o.c. without the lateral bracing. .•— 3• x Ya' diameter Partitions to resist 5 lbs /p.s.f. transverse load.
