A recent scientific research, carried out by eight European institutions, produced a map of the ground-snow-load characteristic value, by using the observations at 2600 meteorological stations placed all over the European territory. Such a map represents the result of the most advanced study now available, since for the first time common methods were used to select and process data collected at the European scale. For this reason the map has been inserted within the EN version of the Eurocode 1 – Snow load, under the form of an informative annex. For code purposes, a further step is necessary to convert the European snow load map into many national normative maps, which will make part of the National Annex of each single Country. In the present work a normative map is proposed for the Italian territory, with two important simplifications respect to the European map. On first the number of the zones has been reduced to three instead of eight (four for the Mediterranean region and four for the Alpine region), secondly the contour lines of the zones coincide with administrative borders of the Provinces. The proposed normative map has been submitted to validation tests, to verify its correspondence to the physical map and to avoid discrepancies at the State border lines. It represents a first step in the development of a normative map, but such advanced to be at the exam of the Italian competent authorities for its adoption.

Abstract
A recent scientific research, carried out by eight European institutions, produced a map of the ground-snow-load characteristic value, by using the observations at 2600 meteorological stations placed all over the European territory. Such a map represents the result of the most advanced study now available, since for the first time common methods were used to select and process data collected at the European scale. For this reason the map has been inserted within the EN version of the Eurocode 1 – Snow load, under the form of an informative annex. For code purposes, a further step is necessary to convert the European snow load map into many national normative maps, which will make part of the National Annex of each single Country. In the present work a normative map is proposed for the Italian territory, with two important simplifications respect to the European map. On first the number of the zones has been reduced to three instead of eight (four for the Mediterranean region and four for the Alpine region), secondly the contour lines of the zones coincide with administrative borders of the Provinces. The proposed normative map has been submitted to validation tests, to verify its correspondence to the physical map and to avoid discrepancies at the State border lines. It represents a first step in the development of a normative map, but such advanced to be at the exam of the Italian competent authorities for its adoption.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
