  • Use of galvanized box nails may result in shear walls with a shear capacity significantly below the nominal unit shear capacities given in SDPWS.
  • Thus, the majority of WSP shear walls have a shear capacity with a high degree of design value variability. This may have unintended consequences that are unknown and unappreciated by the professional engineering and/or building design community.
  • Once SBCA and SBCRI were certain their testing and engineering analysis was consistent and repeatable, they were persistent in bringing all WSP shear wall performance issues to the attention of APA, AWC, ICC-ES and ICC.
