Plane SV Wave in Layered Media – Nonlinear coupling of soil amplification and topographic effects.

Response of a plane strain dam-like topography on the surface of soil overlaying elastic bedrock. The flat ground on either side of the dam is covered by soft sediments with impedance contrast 1:4 with the underlying soil.

Diffraction of vertically propagating plane shear wave incident on a narrow wedge; surface waves generated by diffraction at the toes of the wedge constructively interfere at the tip, way after the incident wave arrives.

Response of a plane strain dam-like topography on homogeneous elastic soil.

Simulation of a centrifuge test on topography effects using dry dense Nevada sand (the constitutive model in our simulation is pressure dependent multi-yield plasticity by Prevost, 1983).

Software

SEISMOSOIL: A software package for 1D site-specific respose analysis

We are pleased to announce the latest release (v1.3) of SEISMOSOIL, our software package for analysis and signal processing of 1D site-specific response problems. As of now, SEISMOSOIL has the following routines:

Linear visco-elastic analysis in the time- and frequency-domain (Haskell, 1958);

Equivalent linear (Seed & Idriss, 1970); and equivalent liner frequency-dependent (Asimaki & Kausel, 2000);

Total stress nonlinear analysis with our Hybrid Hyperbolic model, with Masing and non-Masing hysteresis rules;

Input parameter calibrarion for nonlinear total stress models using genetic algorithms;

Signal processing tools such as Fourier & Response Spectra, Baseline correction, Bandpass Filtering etc.

and a series of graphical output tools to plot your results in Matlab environment.

System requirements

Operating system: Windows 7 and 8/8.1 (64-bit), Mac OS X (Mavericks and Yosemite)

Memory: > 2 GB

CPU: No limitations (SEISMOSOIL can be used in multi-core environment)

Installation
