The program SISMICA LOCALE 1D (One-Dimensional Local Seismic Response) allows the evaluation of the propagation pattern of seismic waves, which have their source in the seismic bedrock and destination the site of interest.
TYPES OF WORKS
The program is used to determine the response spectra for any work for which a local seismic response analysis is required.
CALCULATION METHODS USED
Equivalent Linear Analysis in the frequency domain using the Kelvin-Voigt visco-elastic model:
-Transformation of accelerograms in the frequency domain through Fourier series development
-Determination of transfer functions using non-linear decay curves of tangential elastic modulus and damping factor
-Deconvolution of the signal in the frequency domain through transfer functions
-Determination of response spectra for each boundary state considered
INPUT DATA
Basic seismic data for each boundary state considered
Stratigraphic characterisation of the site
Set of spectrum-compatible accelerograms for each boundary state considered
