Welcome to SoilStructure (Substructural Engineering Software)

SoilStructure Software, Inc. specializes in developing SubStructural Engineering & Geotechnical Engineering software. We develop engineering software for Retaining Walls, Temporary Shoring, Drilled Pier Foundations and Geotechnics.  

We have made this website secure for your convenience & trust. We return emails within 12 hrs.

we specialize in the calculations of only below grade structures.  This requires careful consideration of layered non-linear soils analysis and design of steel piles & reinforced concrete foundations. Most of our programs are the result of an interaction of a seasoned geotechnical engineer, a licensed structural engineer with elegant solution skills and a passionate computer scientist with glitch free software programming. Our clients realize tedious calculations and many hours are more costly than a commercial software. SoilStructure software gives you competitive advantage- robust, glitch free and maintenance cost free software.

We have two methods of software licensing system. A 6 month LEASE tied to a single PC & a USB key PURCHASE that is perpetual and can be used on any number of PC’s- one at a time.

NEW and just released is our cantilever/basement retaining wall program. We have included the provisions ACI 318-14 with additional improvements.  These include unusual surcharges, lateral & moment loads anywhere on the stem and detailing diagram. We have 4 methods of defining static earth pressures and 3 methods of entering seismic earth pressures. We consider cohesion in the passive zone and you can check the allowable maximum temporary vertical cut. Learn More.

When you have a complex drilled shaft foundation project to analyze or design, you can rely on our Drilled Pier software. There is no need to use a simplified spreadsheet that does not take in to effect SoilStructure interaction. Drilled Pier solves lateral load forces through pile on elastic foundation approach. The reinforcement design goes beyond just Pu & Mu. We also consider Vu, Tu and T & V ratio. In addition uplift, negative skin friction and fixed or free head boundary conditions can be modeled. Takes just an hour learning curve. Learn more.

When you have to design a multilevel tieback soldier beam wall, TBWall is the most realistic tool to use. Learn more.

Sometimes you have a round footing or a combined footing with biaxial moments & multiple pedestals, then Shallow Foundation software is needed. Shallow Foundation software also performs bearing capacity analysis for continuous, square, rectangle and round footing shapes. It gives you bearing pressures and factors of safety for uplift, sliding & overturning. Learn more.

On the geotechnical software side, you can analyze liquefaction & seismic settlement effects using the LiquefactionSPT software. You can also compute your lateral displacement magnitude. This software complies with requirements of Special Publication 117A, California Geological Survey, 2008. It computes liquefaction safety factor, seismic settlements and lateral spreading. Learn more.

If you have a driven pile or composite pile with just lateral loads but multi-layered soil deposits, you can get results with SoilStructure Lateral Foundation software. Learn more.

When you have embankments or soft deposits, Settlement Analysis software will remove tediousness from your work. It is perfect for water tanks. Learn more.

The most common feedbacks we get are “SoilStructure software is very easy to use” and “This is exactly what I wanted”. When saving time, avoiding tedious calculations and standardizing your output is paramount get SoilStructure software.

We have four SubStructural software (Drilled Pier, Cantilever/Restrained retaining wall, Shallow Foundation & Tiebwack Wall Design).  We also have three Geotechnical Engineering software (liquefaction analysis, settlement analysis and laterally loaded single pile analysis).  We invite you to download all of our DEMO and take it for a spin.

Two motivations to get your SoilStructure software now:

  1. Immediate access codes sent by email while we prepare your USB key to ship. (Perpetual PURCHASE)
  2. Immediate access codes sent for a PC (6 month LEASE).  See STORE for all engineering software.
