SEISM-HOME allows obtaining the seismic input required for nonlinear dynamic analyses, for any site of the Italian territory and for the return period of 475 years.
The seismic input is defined in terms of a group of seven real accelerograms, recorded on outcropping bedrock and spectrum-compatible, on average, with the code spectra defined in NTC08.
These accelerograms can be directly used for analyses of structural and geotechnical systems located on rock or, otherwise, as input for local site response analyses in case of non-rocky sites.

The accelerograms were selected with maximum care by expert users, avoiding in particular to have more than one record from the same event or from the same station. By means of an optimised procedure (Corigliano et al., 2012), the best set of spectrum-compatible real accelerograms recorded on outcropping bedrock (soil type A) was selected from the main accredited strong-motion databanks. However, the EUCENTRE Foundation refuses all responsibility deriving from the use of the records downloaded from this site and the results obtained from analyses of structures and geotechnical systems using these accelerograms. Despite the numerous checks that were carried out, the final user must be aware of the possible errors that could have been introduced in the process of signal recording, correction and attribution to the site of interest. Moreover, the EUCENTRE Foundation refuses all responsibility for possible malfunctioning of the web site or possible interruption of this service.

PROCEDURE FOR THE SELECTION OF ACCELEROGRAMS
Selection of the site of interest
To obtain a set of real accelerograms, recorded on rock and spectrum-compatible with the NTC08 response spectrum for a 475-years return period, it is necessary to select the site of interest and hence to download the set of records.
The site of interest, for which records are needed, can be selected in different ways, as illustrated in the following.
1) Selection from the map
By clicking on the map, it is possible to increase the level of zoom and hence visualise the region of interest with the corresponding municipalities.
Similarly, it is possible to increase the level of zoom on the municipalities. The level of zoom can be modified at any time using the bar located at the top left corner of the map, or otherwise directly using the mouse.
2) Selection by form
As an alternative, it is possible to use the select site form, located in the column to the left of the map.
After selecting the region and province of interest, by clicking on the “Select” tab at the bottom left of the form, the list of corresponding municipalities would appear. By clicking on the municipality of interest, the maximum level of zoom would be automatically set and centred on this municipality.
3) Selection by geographical coordinates (latitude and longitude)
In the “Select municipalities” tab, it is also possible to insert geographical coordinates of the site of interest (latitude and longitude). Clicking on “search”, the map would show the corresponding point, with a higher level of zoom.
It is possible to switch from the visualisation to the record selection mode by clicking on the “Select” button on the bar at the top of the map. In the browse mode, the mouse pointer would show a cross shape. At this point, clicking on the map would not modify the level of zoom, but rather select the accelerograms for the point closer to the mouse pointer. It is hence possible to switch back to the visualisation mode by clicking on the button “Browse”, which is now replacing the button “Select”.
When a point has been selected, a window showing the localisation of the selected point in terms of municipality, province, region and geographical coordinates would appear. This allows checking that the selection is correct. An orange marker would also show the selected point on the map. By clicking on the envelope, it is hence possible to send the set of records of the selected point to a given email address.
