Welcome to DEEPSOIL
DEEPSOIL is a 1D site response analysis program with graphical user-interface that can perform both:
- 1D Nonlinear analysis
- 1D Equivalent linear analysis
We welcome your feedback. If you are interested in contributing to DEEPSOIL development, please contact Professor Youssef Hashash at hashash@illinois.edu.

November 9, 2011 - DEEPSOIL v5.0.0 Released
DEEPSOIL v5.0.0 is now available for download. This build is recommended for all users. Please login here and download the updated installer. Updates in this release include:
- DEEPSOIL is now offered in a 64-bit compatible version.
- The DEEPSOIL user interface has been updated using the latest .NET components (.NET 4.0).
- DEEPSOIL will now display the progress of an analysis within the interface (all platforms) and in the taskbar (Windows7 only).
- DEEPSOIL will now prevent the system from “sleeping” while an analysis is running.
- The motion library has been improved. It now includes the acceleration, velocity, and displacement time histories, the response spectrum and the Fourier amplitude spectrum.
- The library can also scale input motions to a desired acceleration or by a chosen scale factor.
- The computational core has been optimized for Windows7.
- DEEPSOIL can now calculate the response spectrum using three methods: Newmark Method, Duhamel Integral, and Frequency Domain (default). This is set during each analysis on step 4.
- Baseline correction, site-class conversion, and curve fitting code has been rewritten and optimized.
- DEEPSOIL is now associated with .dp files. Profiles can now be opened from Windows Explorer, allowing a profile to be opened without needing to open DEEPSOIL first.
- DEEPSOIL now calculates and displays the implied strength profile based on the soil properties entered in step 2.
- New input motions have been included. All motions are taken from the PEER Strong Motion Database. Metadata for these motions can be found at the end of the manual.
- Corrected vertical stress calculation for layers above the water table during post-processing.
June 8, 2011 - DEEPSOIL v4.0.4 and New Website
DEEPSOIL v4.0.4 is now available for download. This build adds a the option to use the Menq (2003) formulation to develop modulus reduction and damping curves. A new response spectra summary plot has also been added to the output window. This release also modifies the auto-update functionality within DEEPSOIL to reflect the recent changes to the DEEPSOIL website. Please login here and download the updated installer. Please note that the built in auto-updater may not work correctly for all users before updating to version 4.0.4.
May 6, 2011 - DEEPSOIL v4.0.2
DEEPSOIL 4.0.2 is now available for download. This is a maintenance update to address sevearl bugs. This upadte also enables auto-updating. Please login here to download the updated insatller.
April 12, 2011 - DEEPSOIL v4.0 is now available for download
DEEPSOIL v4.0 is now available for download. A number of updates have been made to the program since the release of v3.7, including:
- DEEPSOIL now supports Windows7.
- The DEEPSOIL user interface has been completely recreated using the latest .NET components.
- DEEPSOIL uses new charting tools, providing more-accurate and visually appealing plots.
- Excel output has been vastly improved. Exporting to Excel is now approximately 25x faster and includes plots of profile data.
- Printing has been added. The user can now print plots of input motions, analysis results, PGA profiles, and interation convergence (for equivalent linear analyses).
- The user can now cancel and analysis while it is running.
- DEEPSOIL is now multi-core aware when running batch mode analyses. Up to 4 analyses can be run concurrently in batch mode (note: limited to 1 analysis per core).
- An "Options" form is now included to allow the user to set program defaults. The new windows can be accessed from the "View" menu.
- A motion conversion tool has been added to convert motions from the PEER Strong Motion Database format (.AT2) to the DEEPSOIL format.
- DEEPSOIL now includes a library that allows the user to view input motions and open profiles without the need to start an analysis.
- The natural frequency and period of the soil column is now shown on step 2.
- An input summary has been added to review input paramters.
