Experimental Determination Of The Stiffness And Strength Of Continuity Tie Connections In Large Wood Roof Dipahragms, And Impact On The Collective Chord Model, Caroline Nicole Yarber

Master's Theses

The goal of this thesis is to determine whether continuity ties in large wood diaphragms are stiff enough to engage and provide diaphragm flexural stiffness in a collective chord model. Four series of continuity tie assemblies using Simpson Strong-Tie steel connectors were tested to determine the stiffness of each assembly. The results found from testing were applied to an example building and then analyzed using both the traditional chord method and the collective chord method.

The completed analysis on a typical size warehouse building showed that the collective chord model will act inadvertently on an existing building designed with a …
