Detailing Mass Timber Structures to Minimize Impacts of Differential Movements

As the height of mass timber buildings continues to grow, so too does the level of design and detailing knowledge required to achieve optimal building construction and performance. A necessary consideration for mass timber buildings of any height is vertical movement—including column shrinkage, joint settlement, and creep—and this is especially important on tall projects. The main concerns are potential impacts on vertical mechanical systems, exterior enclosures, and interior partitions, as well as differential vertical movement of the timber framing systems relative to building elements such as concrete core walls and exterior facades. This presentation will analyze reasons for vertical movement (short and long term), provide methods of calculating anticipated movement such as creep, crushing and shrinkage, highlight detailing options to minimize and accommodate movement, and discuss strategies implemented on mass timber projects completed in North America.
