Wood is a hygroscopic material - it will absorb moisture or give off moisture as it acclimates to its surrounding climatic conditions. As it does this, its cross-grain dimensions will change. Moisture absorption causes material expansion while moisture decrease causes materials shrinkage.
When it comes to mass timber, understanding how, when and why this material movement occurs is key to understanding how to detail to avoid it. During this week's Two Minute Tuesday, the focus is on two particular types of connections in mass timber buildings: beam/column connections and panel to panel connections, and how we as design professionals can detail these conditions to minimize the cumulative effects of shrinkage and expansion.
