Understanding how roof and floor systems (commonly called diaphragms by structural engineers) that are built from Pacific Northwest-sourced cross-laminated timber (CLT) panels perform in earthquake-prone areas is a critically needed area of research. These building components are key to transferring lateral forces from wind and earthquakes into the shear walls and down to the foundation. The tests performed in this project will provide data on a commonly used approach to connecting CLT panels within a floor or roof and the performance of the overall system and the screw fasteners. Structural engineers will directly benefit through improved design guidance. A broader benefit will be increased confidence in the construction of taller wood buildings in communities at greater risk for earthquakes.
