The 1999 – 2004 years of the PEER Center Research at UC Berkeley reflected the original research focus on hazardous concrete buildings (frequently termed ‘non-ductile concrete’ as in this 2008 Los Angeles inventory of hazardous buildings) through a strong series of researcher workshops that alternated between Japan and the U.S. annually. Reports from these workshops provide access to the advance of performance based earthquake engineering research in reinforced concrete building design and rehabilitation.

PEER 2000/10 Report

In 2004, an international performance based seismic design workshop was held in Bled, Slovenia reflecting the evolution of PEER’s research focus to broader, performance based earthquake engineering techniques and procedures for different structures and geotechnical environments –

Performance-Based Seismic Design: Concepts and Implementation, Proceedings of the International Workshop, Bled, Slovenia, 28 June-1 July 2004

The performance based approach to seismic engineering of structures was first outlined (in the U.S. at least) in the 1995 SEAOC – “Performance based seismic engineering of buildings – Vision 2000″ document.

New Zealand Earthquake (2010-2011) Commission Reports

Posted by cdj On January - 17 - 2013

After the Christchurch, New Zealand, earthquakes of 2010 and 2011, the Canterbury Earthquakes Royal Commission of Inquiry was established to report on the causes of building failure as a result of the earthquakes as well as the legal and best-practice requirements for buildings in New Zealand Central Business Districts. The inquiry began in April 2011 and was completed in November 2012. The Commission website provides very useful report access to an array of informative seismic investigations and reports. Reports include:

Foundations on Deep Alluvial Soils: Technical Report by Professor Misko Cubrinovski and Ian McCahon, August 2011 and short peer-review comment on this report by Professor Jonathan Bray.

Reports and discussions of issues leading to the collapse of the CTV building in professional ‘statements of evidence’ testimony (for example: Professor Nigel Preistley and Professor John Mander), in opinions expressed in the CTV consultants’ report, and in the Expert Panel Report.
