expansion joints in large wood buildings
(OP)
We have a very large 4 and 5 story wood building we are designing and were wondering if anbody has experience with expansion joints in large wood structures. We can't find anything in either text books or the code about them. Has anybody used EJ's in large wood buildings, and if so, what criteria did you use for laying them out? Thank you.





RE: expansion joints in large wood buildings
A major concern for a 4 to 5 story building is the vertical shrinkage of the wood structure. And, if you are using brick veneer, the vertical expansion of the brick.
The shrinkage of wood in the longitudinal direction is so small that normally, it is neglected. The major shrinkage in wood occurs in the direction of the width and thickness.

The other issue I've seen is with the other trades. The wood shrinkage tends to "push up" all the conduit and pipe that doesn't shrink causing havoc with electricity, gas, and water connections and the finish work around them.
