Seismic Evaluation of Storefront Systems through Cyclic Racking Test

The potential seismic performance of three storefront framing systems was evaluated. Racking tests were performed on the Oldcastle BuildingEnvelope TM FG3000, Series 3000 Thermal MultiPlane (3000-TMP), and FG-2000 storefront systems. Planar mockups and mockups with a reentrant corner detail were tested for each storefront system. Testing followed a modified AAMA 501.6 dynamic racking protocol to allow detailed observations of damage progression in the mockups. Mockup design, test setup, and loading protocol details along with test results and observations from the racking tests are presented.
