Sažetak

One of challenging tasks on Croatian accession to European Union is completion of the National Annex to Eurocode 8 (EC 8) that calls for the development of national seismic hazard maps. These maps need to be developed for several return periods (probabilities of exceedance) and should considered both bedrock and soil conditions. The later is especially challenging as it calls for site characterization at a microzonation level, i.e., site characterization based upon VS, 30, SPT blowcounts and undrained shear strength – information available only in the Public Works departments of major cities In this paper, the authors discuss several shortcomings associated with the EC 8 ground type definitions and propose their revision. The authors also present the ongoing work for preparation of the Croatian National Annex to EC 8 and explain rationale for improvement of EC 8 ground type definitions.
