Timber provides attractive earthquake performance characteristics for regions of high seismic risk, particularly its high strength-to-weight ratio; however, current timber structural systems are associated with relatively low design force reduction factors due to their low inherent ductility when compared to high-performance concrete and steel...

The following paper presents the seismic performance of a two storey
post-tensioned Laminated Veneer Lumber (LVL) building during the aftershock sequence
following the MW 6.3 Canterbury earthquake that occurred on 22nd February 2011.
Composed of post-tensioned walls in one direction and post-tensioned frames in the
other, the structure under analysis was originally tested quasi-statically in the structural
laboratories of the University of Canterbury (UoC), Christchurch, New Zealand.
Following testing the building was demounted and reassembled as the offices of the STIC
(Structural Timber Innovation Company) research consortium on the UoC campus with
several significant changes being made to convert the building from its initial use as a test
specimen into a functioning office structure.
