Expansion joints in wood buildings

Expansion joints in wood buildings

Expansion joints in wood buildings

(OP)
I am working on a new 3 story wood building on footings.  The building is 400’ long.  There is no masonry or long runs of steel beams.  The roof is pre-engineered wood trusses and the floors are TJI.  

The issue is if a building expansion joint is recommended.  A joint would definitely be supplied with a steel or masonry building.  Has anyone had experience with a wood building of this side with or without an expansion joint?  Are there any publications addressing expansion joints in wood structures?

RE: Expansion joints in wood buildings

Your wood will be shrinking not expanding.
Use of good construction techniques and having adequate shear walls is important.
