Lin, S.-L.; Uma, S.R.; King, A.B.; Horspool, N.A. 2016 A compiled and extensible database for building damage from the 2010-2011 earthquake sequence in Canterbury, New Zealand. Lower Hutt, N.Z.: GNS Science. GNS Science report 2016/30. iii, 29 p.

Abstract: The 2010–2011 Canterbury earthquake sequence in Christchurch, New Zealand caused widespread building damage. In response to each significant earthquake, local and central government and some private organisations conducted safety evaluation surveys. Furthermore, an extensive network of strong motion stations yielded a large ground motion data set. This report describes the tasks undertaken by the authors in association with their partners to (i) scrutinise and organise the massive amount of collected data; and (ii) derive a compiled and extensible damage database for non-residential buildings. The developed database provides pre-earthquake details of building characteristics, the shaking to which they were exposed, and the damage sustained by them. A distinctive feature of the database is the accumulation of incremental damage between events. The database is made as versatile as possible in order to benefit the myriad of fundamental and applied research communities by means of sharing the database. In addition, lessons learned and future research needs are highlighted and discussed. (auth)
