Timber structures in the Canterbury earthquakesThe September 2010 and February 2011 earthquakes in Canterbury, New Zealand resulted in significant ground excitations that caused severe geotechnical effects and widespread structural damage. A new paper outlines the various forms of damage to different types of engineered timber structures, including timber water tanks.Details of the earthquakes including severity and seismological aspects are described by others. This paper includes engineered timber buildings using glue laminated (glulam) and laminated veneer lumber (LVL), and engineered timber tanks. Domestic house construction is only included to show some unique performance characteristic of timber building components used in residential applications. A full evaluation of the performance of houses during the 2010 earthquake and the 2011 earthquake are provided in other publications. Most of the damage resulted from lateral spreading and high levels of horizontal and vertical ground acceleration. The response of these building types is discussed. Engineered timber structures generally performed well both for life safety and serviceability, with most buildings ready for occupation within a short time following the events.
