structures have been examined adopting a displacement-basedprocedure. Results show that the inter-story drift demands inthe CBD were particularly damaging for all types of structuresbut especially catastrophic for mid-rise RC buildings on shallowfoundations. This is an important finding that may contribute tounderstanding why the CTV and PGC buildings collapsed.ACKNOWLEDGMENTSFinancial support for the expedition to the earthquakestrickenarea and the work outlined in this paper has beenprovided under the research project “DARE,” funded throughthe “IDEAS” Programme of the European Research Council(ERC) under contract number ERC-2-9-AdG228254-DARE.The authors would like to thank Professors John Berrill, MiskoCubrinovski, Stefano Pampanin, and Dr. Umut Akgüzel forproviding data and assisting the authors during their reconnaissancevisit in Christchurch in April 2011.REFERENCESApplied Technology Council (ATC) (1996).
