ACCOMODATING SHRINKAGE IN MULTI-STORY WOOD-FRAME STRUCTURES
By: Bruce Lindsey
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 presentation will describe procedures for estimating wood shrinkage and provide detailing options that minimize its effects on building performance.
Learning Objective 1: Discuss the cellular structure of wood in order to understand how moisture and wood interact, and identify the paths that moisture typically travels.
Learning Objective 2: Explain methods of calculating expected shrinkage in multi-story wood-frame buildings.
Learning Objective 3: Highlight best practice details for accommodating wood shrinkage and differential material movement at conditions such as opening sills, MEP lines and shaft wall connections.
Learning Objective 4: Review considerations and solutions associated with shrinkage effects on structural connections.
