SlenderWall With Nycon-PVA Fiber Reinforcement
During the month of March, 2013, a 12 ft. x 16 ft. SlenderWall panel, containing PVA fiber reinforcement in the 2 inches of architectural precast, successfully completed a series of demanding dynamic tests. The tests were performed by National Certified Testing Laboratories of York, PA and included performing ASTM tests [E283-04, E330-20(10), & E331-00(19)] and AAMA tests [501.4-09 & 501.1] under five different configurations using the same SlenderWall panel.
These tests determine the ability of the SlenderWall external cladding panel to withstand differential pressures and accommodate inter-story drift. During the test protocol, the panel was preloaded and air leakage, static water penetration and dynamic water penetration tests were performed. Following the preload, a uniform load deflection test was performed and the leakage and water penetration tests were repeated. Following this, a 50% overload uniform load deflection test was performed and again the leakage and water penetration tests performed.
The tests included three panel configurations: (1) 6 ft. gravity, 6 ft. lateral, studs on 2 ft. centers; (2) 8 ft. gravity, 8 ft. lateral, studs on 2 ft. centers; and (3) 8 ft. gravity, 8 ft. lateral, studs on 4 ft. centers. The panel passed all tests with “flying colors” and validated the durability and ruggedness of the SlenderWall design. A final test is planned in which the panel will be taken to the point of failure (cracking of the architectural precast).
