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 Test Methods E3090/E3090M, Specification C635, andPractice C636 cover suspension systems, their installat

5、ion, andtesting without special regard to seismic lateral restraint needs.They remain applicable and shall be followed when thispractice is specified.1.4 Ceilings less than or equal to 144 ft213.4 m2 andsurrounded by walls connected to the structure above areexempt from the requirements of this prac

6、tice.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 alternative has been su

7、bstan-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 board which is screw or

8、nail 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 are not required to

9、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 structure shall allow

10、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 independentlyof the o

11、ther. 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 safety, health, and env

20、s of this practicewere based in part on testing done in the 1980s. This, coupledwith general observations from the earthquake prone areas inCalifornia have lead to the original practice.X1.2 Actual earthquake experience (most notablyNorthridge and Loma Prieta earthquakes) has shown that threemain th

21、ings 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 splices andcross/runner/main runner intersections, andX1.2.3 Spreader bars and independent support of sus

22、pen-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 requirement forsafety wires on light fixtures and minimum connectionstrengths in Practice E580/E580M. This

23、 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 raised theawareness of seismic installation requirements in areas withinthe United States where these

24、 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 lead to a need for an expansionof the prescriptive installation requirements. There has beenalso a gene

25、ral 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 interest in clear and conciserequirements for installation of ceiling systems. The result isthis current
