Key Features<\/h2>\n<\/div><\/div>\n\n

Layered soil modelling<\/strong> \u2014 each layer defined by unit weight, shear-wave velocity (Vs), damping, and degradation curves G\/Gmax and D (Seed, Vucetic & Dobry, Idriss, Darendeli & Stokoe).<\/p>\n<\/div><\/div>\n\n

Equivalent-linear iteration<\/strong> \u2014 iterative computation converging on the effective shear strain.<\/p>\n<\/div><\/div>\n\n

Flexible input motions<\/strong> \u2014 user-imported accelerograms, synthetically generated signals (band-pass FFT filtering with seismic envelope), or built-in example records.<\/p>\n<\/div><\/div>\n\n

Comprehensive outputs<\/strong> \u2014 surface PGA, response spectra Sa(T), Sv(T) and Sd(T), amplification function in frequency, elastic and design spectra, and ICMS 2018 normalisation (Fa, Fv, TB, TC, TD).<\/p>\n<\/div><\/div>\n\n

Seismic parameters<\/strong> \u2014 ag, F0 and Tc* computed automatically from coordinates or address for all limit states (SLO, SLD, SLV, SLC).<\/p>\n<\/div><\/div>\n\n

Professional deliverables<\/strong> \u2014 the software generates all the technical reports required for the project.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
