![]() ![]() However, if uplift was the only loading that needed to be resisted by a hurricane tie, why would we publish all those F 1 and F 2 allowable loads in our catalog? Some people are tempted to look only at the uplift reaction, go to a catalog or web app, and find the lowest-cost hurricane tie with a capacity that meets or barely exceeds the uplift reaction. Take a quick look at a truss design drawing, and you will see a reaction summary that specifies the downward reaction, uplift and a horizontal reaction (if applicable) at each bearing location. ![]() This blog post is going to focus on the proper specification of a truss-to-wall connection, the methods for evaluating those connections under combined loading and a little background on those methods (i.e., the fun stuff for engineers). In a previous blog post, I wrote about whose responsibility it is to specify a truss-to-wall connection ( hint: it’s not the truss Designer’s). There are plenty of photos of damage wrought by past hurricanes to prove that the connection between the roof and the structure is a critical detail. So when I started to write this blog post about the proper selection of a truss-to-wall connection, I knew I had found my opportunity – how fitting this quote is! I figured it wouldn’t take too long before I’d find an opportunity to use it. I had to write it down for future reference because of course, all of us here at Simpson Strong-Tie are pretty passionate about connections. I heard this quote recently during a presentation at the Midwest Wood Solutions Fair. “Structures are connections held together by members” (Hardy Cross) ![]()
