Seismic Spectral Parameters

The dataset contains the spectral parameters to be used to define the seismic project action on any point in Italy pursuant to the Technical Standards for Construction referred to in Ministerial Decree 14.01.2008. For each of the 10751 points, identified by an identifier and geographical coordinates (datum ED50), there are the three parameters ag (maximum horizontal acceleration of the terrain), F0 (maximum value of spectrum amplification factor) and Tc (start period of the constant speed section of the spectrum), calculated for the reference ranges of 30, 50, 72, 101, 140, 201, 475, 975 and 2474 years. The data have been published in the Official Journal (Annex B to Ministerial Decree 14.01.2008, G.U.R.I. 4 February 2008, S.O. No. 30) and are on the website of the Board of Governors of Public Works (http://www.cslp.it/cslp/index.php?option=com_content&task=view&id=49&Itemid=20).
