The CFS-NHERI Connection Tests aimed to quantify the cyclic behavior of steel-sheet-to-framing fastener details used in cold-formed steel (CFS) shear walls. Specimens captured different screw layouts, CFS ply thicknesses, that were later embedded in wall-line and building-scale models.

Highlights include:

  • Establishing backbone curves and hysteretic behavior for nonlinear simulations in OpenSees and Abaqus.
