2 . Full-scale shear wall assembly tests
Full-scale shear wall assembly tests are conducted to determine the strength and deflection of a larger shear wall assembly ( Figure 6 and Figure 7 ). The data is analyzed and fit in a predictive analytical model to address varying configurations of coldformed steel , wood thickness , specific fastener combinations and framing spans . See Figure 8 for a representative First Cycle Envelope Curve from a full-scale cyclic / simulated seismic shear wall assembly test . These tests are conducted in accordance with the following standards :
• ICC-ES AC230 Acceptance Criteria for Power-Driven Pins for Shear Wall Assemblies with Cold-Formed Steel Framing and Wood Structural Panels
• ASTM E2126 Standard Test Methods for Cyclic ( Reversed ) Load Test for Shear Resistance of Vertical Elements of the Lateral Force Resisting Systems for Buildings , ASTM International
• CUREE Consortium of Universities for Research in Earthquake Engineering Basic Loading Protocol
