SeismoSoil

Software package for 1D site response analysis and engineering seismology tools

---

SeismoSoil provides the following site response analysis routines:

• Linear visco-elastic analysis in both time and frequency domain
• Equivalent linear analysis
  • Original algorithm (Seed & Idriss, 1970)
  • Frequency-dependent algorithm (Asimaki & Kausel, 2002)
• Nonlinear analysis (total stress) in time domain
  • Masing rule with modified Kondner-Zelasko (MKZ) constitutive model
  • Non-masing rule with MKZ model
  • Non-masing rule with Hybrid Hyperbolic (HH) constitutive model (Shi & Asimaki, 2017)

SeismoSoil also provides the following tools for manipulating earthquake time series:

• Band pass and high/low pass filtering
• Baseline correction of acceleration time histories
• Fourier spectra and elastic response spectra of acceleration time histories
• Goodness-of-fit calculation of two time series
• Parsing of PEER and SMC formatted ground motion records

System requirements

Installation

To run from source:

• No installation necessary
• Just download the source codes and put them in a folder

To run from compiled executable:

• Download executable files and extract to hard drive
• Before running SeismoSoil for the first time, make sure to set up MATLAB Runtime:
  • Go to http://www.mathworks.com/products/compiler/mcr/
  • Download MATLAB Runtime (64-bit, R2017b version) for your operating system
  • Install MATLAB Runtime to your computer

How to run SeismoSoil

To run from source:

• Run SeismoSoil.m from the folder that contains it
• You can also add the folder that contains SeismoSoil.m into your MATLAB search path (by running pathtool from the command window)

To run from compiled executable:

• On Windows
  • Double-click SeismoSoil.exe
• On macOS
  • Place SeismoSoil in the Applications folder
  • Open Terminal and execute: /Applications/SeismoSoil.app/Contents/MacOS/applauncher
