The U.S. Geological Survey estimates that several million earthquakes occur in the world each year. Some, such as the devastating earthquake in Nepal and the series of earthquakes that destroyed infrastructure, homes and communities in Christchurch, New Zealand in 2011, capture global attention.
After natural disasters such as these, rebuilding a city needs to be efficient and cost-effective, with an eye towards resilience in the face of future disasters. Engineered wood building systems like glulam and cross laminated timber, also known as CLT, are well suited to meet these needs as they are often prefabricated offsite and can be quickly installed. That helps communities bounce back from disaster in a shorter time frame while minimizing waste. Furthermore, just as trees flex in high winds, timber structures flex in earthquakes, placing wood construction systems at the forefront of seismic design for resilience.
