New Seismic design standards (SNI 1726:2012) were implemented in Indonesia in 2012 and contain a section on base isolated structures. Few structures and buildings have been base isolated in Indonesia but it is hoped that it will become more commonplace for critical facilities (e.g. hospitals, Emergency Management Centers), critical infrastructure, (e.g. bridges), and buildings of National importance.

In New Zealand, the rebuild of Christchurch city, following the devastating earthquakes of 2010 and 2011, includes many buildings that will be base isolated.

  1. It looks like a very valuable training session. Great to see the extent of base isolation facilities already in Padang and the NZ analogy. Great post thanks!
