The wires are to be angled no more than 450 from the plane of the ceiling. The compression post is attached to the grid at the cluster of wires and extends to the overhead structure. The compression post should be engineered for the application and the longer its length, the more substantial it must be. Typical post material can be made of EMT conduit or steel stud (see Horizontal Restraint below). Note: Information regarding maximum lengths of vertical compression posts is available upon request. The code also allows for the use of rigid bracing. When a rigid member is used in place of wires it can handle loads in two directions (push and/or pull), so only two lateral bracing members at 900 to each other are required. The exemption from lateral force bracing for ceilings less than or equal to 1,000 ft2 (93 m2) should not be confused with the exemption for ceilings less than or equal to 144 ft2 (13.4 m2). The 144 ft2 (13.4 m2) exemption is a blanket exemption from all seismic force requirements (2- inch wall angle, heavy duty main runners, lateral force bracing wires compression posts, etc.). The 1,000 ft2 exemption is only for lateral bracing. The lateral force bracing consists of both the splay wires and the compression post. Exempting lateral bracing exempts both the splay wires and the compression post. The lateral force bracing must start within 6 feet of two adjacent walls. It is not necessary to end the lateral force bracing within 6 feet of the opposite two walls. The last lateral force brace rnust only be within 12 feet of the opposite walls. It is not necessary to run the lateral force bracing wires parallel to the grid layout in plan view. They can be at any arbitrary angle. It is also not necessary that all the lateral force braces have the same orientation. Lateral force bracing should be taut to function correctly.

This clip allows for an alternative installation method using 15/16" wall angle instead of the required 2" wall angle and stabilizer bar construction: Additional benefits are listed below. The CTSPC-2 accessory meets seismic performance criteria set forth by the IBC to stabilize main runners and cross tees at the ceiling's perimeter as detailed in ICC-ES report 3336. CertainTeed Seismic Perimeter Clip (CTSPC2) Installation The CTSPC-2 clip is easy to install. Clearly visible dimension markers on the clip show the required 3/8" or 3/4" clearance of the grid to the wall. The rounded shape of the stop bumps allows for flexible clip adjustment during installation, and screw holes provide easy attachment to the tee when necessary. To Install: Firmly grasp clip and press down overbulb of cut suspension member. It will snap into place with an audible click. (A properly seated clip will be able to move along the cut suspension member.) Engage clip back tabs in desired location behind wall angle. CTSPC-2 Category C: Requirements and Benefits Grid can be tight on two adjoining walls - using the CTSPC-2 clip Intermediate Duty or Heavy Duty main runners Categories D, E, and F: Requirements and Benefits Eliminates 2" wall angle, allows for 15/16" wall angle Grid must be tight on the two adjoining attached walls— use the CTSPC-2 clip or pop rivets Heavy Duty main runners only Use CTSPC-2 clip with 3/4" clearance on unattached walls Benefits of Using the CTSPC-2 Installs easily Saves time and money Meets code requirements Makes it easy to square the system Eliminates stabilizer bars allowing easier access Allows easier access to plenum CertainTeed P9 Technical Support I 1-800-233-8990 I www.certainteed.com/ceilings SMN1GO8MN Ceilings ADDITIONAL RESOURCES ON SEISMIC CODES AND REQUIREMENTS Contact CertainTeed -Ceilings Technical Services Phone: 1-800-233-8990 Visit these code related websites: American Society for Testing and Materials (ASTM): www.astm.org National Institute of Building Sciences: www.nibs.org International Code Council: www.icc-es.org U.S. Geological Survey: www.usgs.gov Ceilings Interior Systems Construction Association (CISCA): www.ClSCA.org American Society of Civil Engineers (ASCE): www.ASCE.org City of Los Angeles Department of Building and Safety:http://netinfo.ladbs.org/rreports.nsf (RR 25978) CERTAINTEED'S SEISMIC SUSPENSION SYSTEMS (ESR-3336) International Code Council (ICC-ES) recognizes CertainTeed's Seismic Suspension Systems as a code-compliant solution (ESR-3336). This evaluation and confirmation by ICC-ES provides evidence supporting the CertainTeed Suspension System and Perimeter Clip System as a code-compliant alternative to IBC requirements. CertainTeed's ICC-ES evaluation allows the utilization of 15/16" wall angle for ceiling installations in IBC Categories D, E, and F when used with the CertainTeed Perimeter Clip (CTSPC-2). OThe ICC-ES allows you to meet seismic code requirements without the risk of delaying your construction schedule and eliminating the need for the conventional IBC installation components (2" wall angle and stabilizer bars). CertainTeed's ICC-ES evaluation also allows the use of two fixed walls instead of a floating ceiling when used with the CertainTeed Perimeter Clip for Category C.

The project requirements, which include the seismic design category, can be found in Section 1 of the specification and on the first page of the structural drawings. Jurisdictions using the 2009 IBC follow ASCE 7-05, Section 13.5.6 and the appropriate CISCA recommendations! guidelines. International Building Code allows two paths to determine Seismic Design category - IBC Section 1613 or ASCE 7 Section 11.6. The IBC states that a Seismic Design Category must be established for each construction project based on: Anticipated ground motion Soil type in a specified geographic area Occupancy category These factors are used to evaluate and establish a Seismic Design Category of A, B, C, D, E or F. The installation of ceilings can be divided into three tiers of increasing requirements: Categories A & B are installed to meet requirements established in ASTM C636. There are no additional seismic requirements. Category C projects must follow ASTM C636 and ASTM E580 (CISCA Recommendations for zones 0-2 can be used if 2009 IBC governs) Categories D, E & F must follow ASTM C636, ASCE 7 Section 13.5.6 and ASTM E580 (CISCA Guidelines for zones 3-4 can be used if 2009 IBC governs) Jurisdictions using the 2012 and 2015 IBC follow ASCE 7-10, Section 13.5.6 and ASTM E580 (which has replaced the CISCA documents).

The code also sets forth limitations and conditions of use. It is important to know that while the building code establishes the requirements, the code official has the power to enforce its provisions. The code official also has the latitude to allow materials and methods of construction that are not addressed in the code. As with all code issues, the local authority having jurisdiction (AHJ) is the final arbiter for application of the IBC at that location.
