(Test Method)Standard Test Methods to Evaluate Seismic Performance of Suspended Ceiling Systems by Full-Scale Dynamic Testing
Standard Test Methods to Evaluate Seismic Performance of Suspended Ceiling Systems by Full-Scale Dynamic Testing
SIGNIFICANCE AND USE
5.1 The test protocol evaluates those complex suspended ceiling systems that cannot be assessed by simple engineering calculations contained in ASCE/SEI 7 and Practice E580/E580M. It is not intended to replace the requirements in ASCE/SEI 7. Suspended ceiling systems are considered nonstructural components of buildings.
SCOPE
1.1 These test methods help evaluate the performance of a full-scale suspended ceiling system during a seismic event using a dynamic seismic simulator (shake table).
1.2 These full-scale procedures are not the only available procedures for evaluating the seismic performance of ceiling systems. These tests do not preclude the use of other small-scale or full-scale component or system testing.
1.3 These test methods contain two independent procedures.
1.3.1 Comparative method where the level of performance of an experimental system is compared to that of a control test system under the same set of conditions.
1.3.2 Non-comparative method where a single test is conducted to establish the level of performance of an experimental system.
1.4 These test procedures are valid and useful for all types of suspended ceiling systems.
1.5 The text of this standard uses notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
The response of nonstructural components, such as suspended ceiling systems, can significantly
affect the functionality of a building after an earthquake, even when the structural components are
undamaged.
Traditional suspended ceiling systems, which consist of typical direct hung “T” shaped main
runners and cross tees, are installed in accordance with the prescriptive requirements contained in
Practice E580/E580M, the applicable sections of the International Building Code, and ASCE/SEI 7.
Specification C635/C635M, Test Methods E3090/E3090M, and Practice C636/C636M cover suspen-
sion systems and do not address seismic restraint of suspension systems or the performance of the
ceiling panels. The performance of these traditional ceiling suspension systems is determined by
mechanical testing of the connection’s strengths and the load-carrying capability of the suspension
members. Practice E580/E580M contains specific instructions concerning the placement of hanger
wires, perimeter fastening, and seismic bracing.

members. Connection strengths of the structural suspension members are not directly related to the
anticipated performance of the system under earthquake loads. In addition, the ceiling panels or tiles
are not always supported on all four sides of the suspension members.The integrity of ceiling systems
depends on the ability of the ceiling infill panels to remain in place during an earthquake and on the
structural integrity of the suspension system. These test methods provide a means to evaluate the
performance of traditional suspended ceilings, as well as many of these nontraditional type ceiling
systems.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

There are nontraditional suspended ceiling systems that do not consist of the typical direct hung “T”
members. Connection strengths of the structural suspension members are not directly related to the
anticipated performance of the system under earthquake loads. In addition, the ceiling panels or tiles
are not always supported on all four sides of the suspension members. The integrity of ceiling systems
depends on the ability of the ceiling infill panels to remain in place during an earthquake and on the
structural integrity of the suspension system. These test methods provide a means to evaluate the
