(Practice)Standard Practice for Installation of Ceiling Suspension Systems for Acoustical Tile and Lay-in Panels in Areas Subject to Earthquake Ground Motions
Standard Practice for Installation of Ceiling Suspension Systems for Acoustical Tile and Lay-in Panels in Areas Subject to Earthquake Ground Motions
ABSTRACT
This practice covers acoustical ceiling suspension systems and their additional requirements in buildings in International Building Code Seismic Design Categories C, D, E, and F. The application of this practice is to be determined by local authorities. Current seismic maps published by recognized authorities such as the International Building Code, the American Society for Civil Engineers, as well as related material such as the United States Geological Survey Open File 82-1033 and MS-812 Seismicity Maps, should be consulted. This practice is not intended to stifle research and development of new products or methods which may simplify the application method specified herein. A variation, however, must be substantiated by verifiable engineering data or dynamic testing. A ceiling area of 144 ft2[13m2] or less, surrounded by walls that connect directly to the structure above shall be exempt from this practice as are gypsum board ceilings on one level surrounded by walls connected directly to the structure above.
SIGNIFICANCE AND USE
This practice is a prescriptive set of installation methods to be used for suspended ceilings and is often used in lieu of designing a separate lateral restraint system. The authority having jurisdiction shall determine the applicability of this practice to local code requirements.
This practice covers installation of suspended ceiling systems and related components in areas that require resistance to the effects of earthquake motions as defined by ASCE 7 and the International Building Code.
The practice is broken into two main sections. The first section covers areas with light to moderate earthquake potential (Seismic Design Category C) while the second deals with severe earthquake potential (Seismic Design Category D, E & F).
This practice includes requirements from multiple sources including previous versions of this practice, CISCA Seismic Recommendations for Direct-hung Acoustical Tile and Lay-in Ceilings, Seismic Zones 0-2 and CISCA Guidelines for Seismic Restraint for Direct Hung Suspended Ceiling Assemblies, Seismic Zones 3 & 4, suspended ceiling requirements from the International Building Code and ASCE 7. The purpose is to combine the requirements from these sources into a single comprehensive document.
SCOPE
1.1 This practice covers the installation of suspended systems for acoustical tile and lay-in panels and their additional requirements for two groups of buildings that are constructed to resist the effects of earthquake motions as defined by ASCE 7 and the International Building Code. These groupings are for Seismic Design Category C and Seismic Design Categories D, E and F.
1.2 The authority having jurisdiction shall determine the applicability of this practice.
1.3 Specification C635 and Practice C636 cover suspension systems and their installation without special regard to seismic lateral restraint needs. They remain applicable and shall be followed when this practice is specified.
1.4 Ceilings less than or equal to 144 square feet and surrounded by walls connected to the structure above are exempt from the requirements of this practice.
1.5 This practice is not intended to stifle research and development of new products or methods. This practice is not intended to prevent the installation of any material or prohibit any design or method of construction not prescribed in this practice, provided that any such alternative has been substantiated by verifiable engineering data or full-scale dynamic testing that is acceptable to the authority having jurisdiction.
1.6 Ceiling areas of 1000 ft2 [92.9 m2] or less shall be exempt from the lateral force bracing requirements of 5.2.8.
1.7 Ceilings constructed of gypsum board which is screw or nail attached to suspended members that support a ceiling on one level extending from wall to wall shall be exempt from the requirements of this practice.
1.8 Free floating ceilings (those not attached dire...
