A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Depa

3、rtment of Defense.1NOTESection 4.2.2 was editorially revised in August 2013.1. 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 earthqu

4、ake motions as defined by ASCE7 and the International Building 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 suspens

5、ionsystems and their installation without special regard to seismiclateral restraint needs. 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 requir

6、ements of this practice.1.5 This practice is not intended 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 alte

7、rnative has been substan-tiated by verifiable engineering data or full-scale dynamictesting that is acceptable to the authority having jurisdiction.1.6 Ceiling areas of 1000 ft292.9 m2 or less shall beexempt from the lateral force bracing requirements of 5.2.8.1.7 Ceilings constructed of gypsum boar

8、d which is screw ornail attached to suspended members that support a ceiling onone level extending from wall to wall shall be exempt from therequirements of this practice.1.8 Free floating ceilings (those not attached directly to anystructural walls) supported by chains or cables from thestructure a

9、re not required to satisfy the seismic force require-ments provided they meet the following requirements:1.8.1 The design load for such items shall equal 1.4 timesthe vertical operating weight.1.8.2 Seismic interaction effects shall be considered inaccordance with 5.7.1.8.3 The connection to the str

10、ucture shall allow a 360range of motion in the horizontal plane.1.9 The values stated in either inch-pound or SI units are tobe regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exactequivalents; therefore, each system shall be used in

11、dependentlyof the other. Combining values from the two systems result innonconformance with the specification.1.10 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safe

This, coupledwith general observations from the earthquake prone areas inCalifornia have lead to the original practice.X1.2 Actual ea

18、rthquake 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 preventdropout,X1.2.2 Minimum strength requirements for splic

19、es 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 support ledge.X1.3 These observations have lead to the requir

20、ement 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 ofsuspension members.X1.4 Advent of International Building Code has r

21、aised 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 that do not use traditionaltee bar suspension systems, has lea

22、d 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 generation of performance basedseismic codes has lead to new inte

23、rest 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 issue (E580/E580M11a) that may impact the use of this standard
