This white paper summarizes the results presented with the webinar “Structural Screw Technology in Tall Wood Buildings”. It is intended to provide guidelines to designers when designing cross laminated timber connection systems. Results from recent testing at the University of BC are presented and directly compared to potential design methods. Using the obtained test data as a baseline and a variety of possible design methods respective over-strength factors are derived. A summary of obtained load displacement curves from testing are presented and detailed design calculations for possible design methods are presented.
