Accommodating Shrinkage in Multi-Story Wood-Frame Structures

In wood-frame buildings of three or more stories, cumulative shrinkage can be significant and have an impact on the function and performance of finishes, openings, mechanical/electrical/plumbing (MEP) systems, and structural connections. However, as more designers look to wood-frame construction to improve the cost and sustainability of their mid-rise projects, many have learned that accommodating wood shrinkage is actually very straightforward.

This publication describes procedures for estimating wood shrinkage and provides detailing options that minimize its effects on building performance.
