How to fasten and join wooden girders . . . and then some.
Hi people,
I have a few questions regarding wooden girders that I’ll be using in my next project. The girders are for a pier-supported deck with living space above. My questions are:
1. How do most of you prefer to fasten your wooden members to the concrete pier? With some PT scraps and a capillary break between the pier and the PT? Or with steel beam anchors (brand names?)?
2. What is the best way for the girders to meet and join over the piers? For example, with a 16’ span, a pier at both ends, and one in the middle, whats the proper detail for joining the two 8’ long girders that meet over the middle pier? Can they just be butted up against one another? What concern and what precautions are taken about moisture problems where the two pieces meet?
3. Without going into the all the specifics, theres a funky detail I am thinking in my head, and wondering if its really possible. I need an 11’ span from a 6×12 girder, but structurally only the first 2’ need to be 6×12. The other 9’ could be a 4×10. Would it work if I made the whole member a 4×10, and nailed 2x blocks around that 2’ section, beefing up that 2’ section to a 6×14? Possible moisture problems here?
Thanks, if any of you have any insight into some of these questions,
Dan

Must be engineereze, I know not of what you speak.
thanks.
If I'm on the same wavelength as JH
There's a brand name for those kind of fasteners that's almost as generic as "Kleenex", but I'm having a senior moment right now. Can't even come close to finding them on Google. Think old wooden bridges. Old timber framed trusses, etc.
