Pont Consultants Ltd has been engaged by Ecoplus Systems to provide assistance with the preparation of a seismic design manual to ensure that installation of the FasTLock Suspended Ceiling Systems will meet the requirements of Clause B1 of the New Zealand Building Code with respect to seismic designTesting of the ceiling grids and perimeter fixings was undertaken in. Robust to resist lateral forces and maintain structural integrity during a seismic event. BENEFITS OF ARMSTRONG SEISMIC SOLUTIONS.
Comprehensive solutions for Two Way and Dry Wall Ceiling Systems. Depending on the room size and seismic loads we will design either a perimeter fixing or plenum bracing option for your Rondo Ceiling System so that the seismic forces are adequately transferred to the structure. Each area shall be capable of allowing or.
Perimeter support wires within 8 Ceiling areas over 2500 SF must have seismic separation joints or full height partitions. Seismic Recommendations for Direct-hungAcousticalTile and Lay-in Ceilings Seismic Zones 0-2 and CISCAGuidelines for Seismic Restraint for Direct Hung Suspended Ceiling Assem-blies Seismic Zones 3 4 suspended ceiling requirements from the International Building Code and ASCE 7. The requirements for a suspended ceiling are determined by the buildings Seismic Design Category.
Determination of the Seismic Design Category is complex and must be determined by a Registered Architect or Professional Engineer and should be found in the construction docu-mentation. During a seismic event damage can occur within the ceiling system when the vibrations and movement throughout the structure differ from the surrounding building and other nonstructural components such as non-load-bearing partition walls. USG Donn Brand CE Controlled Environment 1 - 12in.
12-gauge hanger wires shall be attached to the suspension members within three inches of each corner of each fixture. However in the absence of a specific AC for this purpose IC-ES allowed AC156 to act as the basis for all seismic testing and evaluation for the acoustical ceiling suspended ceilings industry. ES4 expansion sleeve is used to.
Standard Seismic Applications Guide - IBC Category C. Research and tests demonstrated that industry seismic standards UBC Standard 25-2 were not adequate. Ceiling areas over 1000 SF must have horizontal restraint wire or rigid bracing.
In the event of an earthquake our seismic-rated ceiling systems help support life safety and the preservation of property. Armstrong Ceiling Solutions offers an ICC-ES approach to installations in IBC Categories C D E and F. Ceilings without rigid bracing must have 2 oversized trim rings for sprinklers and other penetrations.
All continuous ceiling areas exceeding 2500 ft 2 232 m2 shall have a seismic separation joint bulkhead braced to the structure or full-height partition that breaks the ceiling into areas of no more than 2500 2ft2 232 m and a ratio of the long to short dimension less than or equal to four. Seismic-compliant solutions In geographic seismic zones and other building types requiring additional protection building structures need to be properly designed and engineered to withstand seismic effects while sustaining an acceptable level of damage. Armstrong SEISMIC RX ICC-ES recognizes Armstrong SEISMIC RX Suspension Systems as seismic.
Seismic construction standards have been established to control panic during an earthquake and provide life safety to building occupants during and after an earthquake. GRIDLOK bracing for Ceiling Systems exclusive distributor in Australia Rondo seismic ceiling systems. The pur-pose is to combine the requirements from these sources into a.
Allows the ceiling to be divided at a splice on the main beam to accommodate the IBC mandate for ceiling areas greater than 2500 SF to have seismic separation joints. The following are all the IBC Category C 2 Code Requirements for lay-in acoustical panels and direct-hung acoustical tiles. Seismic standards generally apply to ceilings larger than 144 square feet.
The Seismic Design Category is determined from the. When intermediate-duty systems are used No. View an alternate solution that delivers additional options.
USG Donn Brand DXDXL Standard 1516in. Please refer toAC3235 for more information. USG Donn Brand DXDXL Concealed 1516in.
