strapping in a wood building
(OP)
Hi all,
I saw a project recently that was a single story wood building. On all the top plate corners around the building, the engineer of record had installed horizontal straps to be wrapped around the corner. I hadn't seen this before and wasn't sure why the engineer had called it out. Is it a CBC specification? Any help is appreciated.

RE: strapping in a wood building
I use a detail that requires the top plates to be staggered at the corners so that the nails at the connection are in direct shear for internal pressure loads. Another detail requires at least 3 studs at wall corners for the same reason. I think these kinds of details (including yours) are used to provide redundancy and ensure minimal structural stability/integrity, since the calculated loads go through the diaphragms and then through the sidewall and endwall roof and base connections.
In what area will the structure be located?

In complicated wood buildings, my office will sometimes use steel straps at the corners. It's not required by the code (as far as I know except for single top plates), but we feel that it can add some redundancy to the structure and straps are relatively cheap.
