AC3235 Seismic Certification with DH SEISMIC CLIP-signed.pdf Donn Seismic Solutions ® Performance Categories D, E, and F Category C Rec'd 8/14/2015 Since 1957 D® brand suspension systems have set the standard, using the strongest gauge steel to produce ONN the tightest systems available with the greatest lateral and torsional stiffness. Building on this commitment to quality, USG teamed with the University at Buffalo (SUNY), the Department of Civil, Structural and Environmental Engineering – Structural Engineering and Earthquake Simulation Laboratory (SEESL) to conduct full-scale seismic testing to evaluate and qualify the seismic performance of these systems. This testing proved that D ONN suspension systems provide a superior code-compliant solution to meeting International Building Code (IBC) requirements, including installations in Categories D, E and F, and Category C. D suspension systems to: ONN – Meet or exceed all national code requirements with 7/8 wall molding. – – Provide evidence of compliance (and greatly exceed) ICC Evaluation Service, Inc. (ICC-ES) AC156 and AC368 requirements. – Deliver proven code-compliant solutions 42% stronger than competing systems. – Offer an aesthetically attractive option to traditional 2 angle molding. – – Offer a cost-saving Intermediate Duty system without perimeter wires that exceeds the requirements of AC156 and AC368. Seismic Seismic testing typically focuses primarily on the suspension system itself. Any ceiling panel can be installed equipment are usually excluded. In practical application, however, the suspension system must support and carry the weight of a fully functional ceiling system, including ceiling panels that can weigh as much as 2 lb./sq. ft. Therefore, USG tested suspension systems with weights commensurate with those found in real-world USG offers. Full-scale testing performed at the University at Buffalo (SUNY) the department of Civil, Structural and Environmental Engineering – Structural Engineering and Earthquake Simulation Laboratory (SEESL) by competing systems.
