Dynamic and Cyclic Load
QAI offers architects and designers comprehensive mock-up testing capabilities to ensure their curtain walls are properly designed and will function as expected.
These tests determine the performance of fenestration systems installed into buildings that are subjected to impact and cyclic static pressure differentials, which may represent windborne debris and pressures in a windstorm environment.
QAI is not restricted; your largest mock-ups could be constructed and tested outdoors. The results of our testing are used to validate the design, workmanship, material selection, and to gain the approval of clients, architects, and or consultants.
Dynamic and Cyclic Load are performed according to AAMA, ASTM, ANSI, CPSC, Architectural Project Specifications, and other standards or test programs. Tests can involve precast structures, metal/glass, exterior skins, live or dead loads. Custom test conditions can be devised by QAI experts to measure other performance attributes.
Test methods and specifications used to obtain data for Dynamic and Cyclic Load:
- Wind Resistance
- Air Infiltration
- Static & Dynamic Water Resistance
- Condensation
- Structural Loading
- Thermal Cycling
- Impact Safety
- Acoustics
- Interstory Displacement (vertical movement)
- Dynamic Seismic Performance (lateral movement)
- Thermal Transmittance
- Sealant and Gasket Durability
