Parametri Sismici NX

Seismic hazard parameters and response spectra to NTC 2018, right in the browser. Pick a site on the map to read ag, F0 and Tc* for every return period, then build elastic and design response spectra with an AI assistant at your side.

Key features

NTC 2018 hazard grid — pick a location on the map or type coordinates and the app interpolates ag, F0 and Tc* from the official national grid for every return period.

Response spectra for every limit state — elastic and design spectra for SLO, SLD, SLV and SLC, with soil category and topographic amplification, plotted interactively.

Seismic coefficients — horizontal and vertical seismic coefficients (kh, kv) and amplification factors computed to NTC.

AI chat assistant — an interactive assistant that answers seismic-domain questions and fills in the parameters for you, in several languages.

PDF report & GeoDropbox — export the spectra as a PDF report and save or load your project from GeoDropbox cloud storage.

Who it is for

Geotechnical and structural engineers, geologists and designers who need NTC 2018 seismic input — hazard parameters, coefficients and response spectra — for foundations, retaining works and buildings.
