The first two Standard of Care articles discussed deferred submittals and truss-to-truss connections. This article explores truss minimum required bearing width issues from the perspective of the design community.
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.
The truss industry’s innovative products and software form the link between new science-based discoveries and their application.
The mission of any professional engineering endeavor is to deploy innovative materials, designs or methods of construction that meet or exceed all regulations, protect the consumer and preserve free and unfettered competition as the rule of trade.
