Inelastic Reponse Spectra for the Christchurch Earthquake Records

This report by Professor Emeritus Athol Carr, Department of Civil and Natural Resources Engineering, University of Canterbury  is intended to assist structural engineers in the task of interpreting the observed performance of buildings in the Christchurch earthquakes of 2010 and 2011. 

Commission's summary of the report  (.PDF) 218kb

Owing to its large size, the report has been broken into the following segments: 

Contents; introduction; displacement ductility; response spectra; the use of acceleration and displacement response spectra in building design; factors that influence response spectra values; response spectra for the Christchurch central business district.  (.PDF) 1.3mb

Earthquake horizontal components for 4 September 2010, 22 February 2011, 13 June 2011; 22 February 2011 earthquake vertical components; relationship between the observed and design response spectra.   (.PDF) 1.7mb

Variations in inelastic spectra due to inelastic modelling assumptions; the significance of the Christchurch earthquakes in relation to design values; factors that influence the lateral displacement of buildings; force reduction factors; conclusions; references.  (.PDF) 972kb
