3、of the U.S. Department of Defense.1. Scope*1.1 This practice covers the installation of suspended systems for acoustical tile and lay-in panels and their additionalrequirements for two groups of buildings that are constructed to resist the effects of earthquake motions as defined byASCE 7 andthe Int

4、ernational 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 witho

5、ut special regard to seismiclateral 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 fromthe requirements of this practice.1.5 This prac

6、tice is not intended to stifle research and development of new products or methods. This practice is not intendedto prevent the installation of any material or prohibit any design or method of construction not prescribed in this practice, providedthat any such alternative has been substantiated by v

7、erifiable engineering data or full-scale dynamic testing that is acceptable tothe 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

8、to suspended members that support a ceiling on onelevel extending from wall to wall shall be exempt from the requirements of this practice.1.8 Free floating ceilings (those not attached directly to any structural walls) supported by chains or cables from the structureare not required to satisfy the

9、seismic force requirements provided they meet the following requirements:1.8.1 The design load for such items shall equal 1.4 times the vertical operating weight.1.8.2 Seismic interaction effects shall be considered in accordance with 5.7.1.8.3 The connection to the structure shall allow a 360 range

10、 of motion in the horizontal plane.1.9 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of theother. Co

11、mbining values from the two systems result in nonconformance with the specification.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use.

19、e based in part on testing done in the 1980s. This, coupled withgeneral observations from the earthquake prone areas in California have lead to the original practice.X1.2 Actual earthquake experience (most notably Northridge and Loma Prieta earthquakes) has shown that three main things arecritical f

20、or good performance of ceiling systems during earthquakes which are:X1.2.1 Independent safety wires on light fixtures to prevent dropout,X1.2.2 Minimum strength requirements for splices and cross/runner/main runner intersections, andX1.2.3 Spreader bars and independent support of suspension member t

21、erminal ends at wall closures which prevent panel dropoutif the perimeter suspension terminal end slips off of the closure support ledge.E580/E580M 1610X1.3 These observations have lead to the requirement for safety wires on light fixtures and minimum connection strengths inPractice E580/E580M. This

22、 also led to the requirement for 2-in. 50 mm perimeter support ledger and the requirement forindependent support of terminal ends of suspension members.X1.4 Advent of International Building Code has raised the awareness of seismic installation requirements in areas within theUnited States where thes

23、e requirements traditionally were not a concern.X1.5 The introduction of non-traditional ceiling made of wood and metal, as well as ceilings that do not use traditional tee barsuspension systems, has lead to a need for an expansion of the prescriptive installation requirements. There has been also a

24、 generalconcern over the interaction of the ceiling system with HVAC components, lights and sprinklers. This coupled with the comingof next generation of performance based seismic codes has lead to new interest in clear and concise requirements for installationof ceiling systems. The result is this
