THE IMPORTANCE OF BRINGING ENGINEERS AND SEISMOLOGISTS TOGETHER: MEMORIES OF DUBROVNIK

Professor Marco Mucciarelli has always recognised the importance of, and has been a strong advocate for, close linkages between earthquake engineers and seismologists. In September of 2007, an Advanced Research Workshop was organized on Marco's suggestion, as a follow-up to a NATO Science for Peace Project. It brought together 30 earthquake seismologists and engineers from 14 countries around the world, with the goal of helping to improve seismic safety. The workshop took place in Dubrovnik and was organised by Marco and Croatian project partners. It resulted in the Springer book “Increasing Seismic Safety by Combining Engineering Technologies and Seismological Data”. This presentation will summarise the key questions addressed at the Dubrovnik meeting, a summary of progress made, and some of the outstanding questions that remain today. Important topics that were addressed included: 1) how can ambient noise data be used to characterise both soil and building response ; 2) how to separate frequency decrease due to distributed or concentrated damage, timevarying building and soil behaviour ; 3) what is the role of transients in ambient noise analysis ; 4) what is the role of building-soil resonance in damage patterns ; 5) how to understand soil and building non-linear behaviour? A few of the key, practical results from this meeting include: 1) suggested modifications to existing building codes for soil classification, and 2) simplified approaches to estimating building vulnerability and soilbuilding resonance for use in practise in cities. Results from this meeting have advanced both earthquake science and earthquake engineering. The science that resulted from this meeting was important – but just as important were the new linkages and partnerships that developed between seismologists and engineers from all corners of the world. Those partnerships continue to this day, thanks to Marco.
