3、epartment of Defense.1. Scope*1.1 This practice covers the installation of suspended sys-tems for acoustical tile and lay-in panels and their additionalrequirements for two groups of buildings that are constructedto resist the effects of earthquake motions as defined by ASCE7 and the International B

4、uilding Code. These groupings are forSeismic Design Category C and Seismic Design Categories D,E and F.1.2 The authority having jurisdiction shall determine theapplicability of this practice.1.3 Specification C635 and Practice C636 cover suspensionsystems and their installation without special regar

They remain applicable and shall befollowed when this practice is specified.1.4 Ceilings less than or equal to 144 square feet andsurrounded by walls connected to the structure above areexempt from the requirements of this practice.1.5 This practice is not intend

6、ed to stifle research anddevelopment of new products or methods. This practice is notintended to prevent the installation of any material or prohibitany design or method of construction not prescribed in thispractice, provided that any such alternative has been substan-tiated by verifiable engineeri

17、 Seismic Zones3 earthquake; seismic; seismic re-straint; suspended ceilingAPPENDIX(Nonmandatory Information)X1. COMMENTARYX1.1 Recommendations in previous versions of this practicewere based in part on testing done in the 1980s. This, coupledwith general observations from the earthquake prone areas

18、inCalifornia have lead to the original practice.X1.2 Actual earthquake experience (most notablyNorthridge and Loma Prieta earthquakes) has shown that threemain things are critical for good performance of ceilingsystems during earthquakes which are:X1.2.1 Independent safety wires on light fixtures to

19、 preventdropout,X1.2.2 Minimum strength requirements for splices andcross/runner/main runner intersections, andX1.2.3 Spreader bars and independent support of suspen-sion member terminal ends at wall closures which preventpanel dropout if the perimeter suspension terminal end slips offof the closure

20、 support ledge.X1.3 These observations have lead to the requirement forsafety wires on light fixtures and minimum connectionstrengths in Practice E580/E580M. This also led to the require-ment for 2-in. 50 mm perimeter support ledger and therequirement for independent support of terminal ends ofsuspe

21、nsion members.X1.4 Advent of International Building Code has raised theawareness of seismic installation requirements in areas withinthe United States where these requirements traditionally werenot a concern.X1.5 The introduction of non-traditional ceiling made ofwood and metal, as well as ceilings

22、that do not use traditionaltee bar suspension systems, has lead to a need for an expansionof the prescriptive installation requirements. There has beenalso a general concern over the interaction of the ceiling systemwith HVAC components, lights and sprinklers. This coupledwith the coming of next gen

23、eration of performance basedseismic codes has lead to new interest in clear and conciserequirements for installation of ceiling systems. The result isthis current rewrite of this practice.SUMMARY OF CHANGESCommittee E33 has identified the location of selected changes to this standard since the last
