ASDIP RETAIN Structural Engineering Software

Design Your Retaining Walls Easily Within Minutes


ASDIP RETAIN is structural engineering software utilized by engineers for design of retaining walls. ASDIP RETAIN is based upon the latest IBC / ACI 318 specifications.

ASDIP RETAIN software is also able to design masonry stems per the latest MSJC provisions. ASDIP RETAIN substantially simplifies time-consuming calculations for structural engineering design.

Key benefits:

  • Quickly model your retaining walls with the simple and efficient graphical user interface.
  • Confidently optimize your design and comply with design Code provisions.
  • Impress clients and plan-checkers with eye-catching condensed or detailed reports.
  • Extensive documentation, solved examples, and blog posts to guide you throughout the software.
  • Use your valuable time wisely while ASDIP RETAIN does the hard work for you.


  • Any Windows® Operating System. No additional software required.
  • Full compliance with:
    • IBC-12
    • ACI 318-11
    • MSJC-11
  • Stem material can be concrete, masonry, or combination of both.
  • The restrained walls can be either fixed or pinned at base.
  • Full set of design code load combinations.
  • Specify water table location in the backfill.
  • Customizable design criteria, options, and conditions.
  • Three different unit systems available:
    • US (in, ft, Kip, ksi)
    • SI (cm, m, N, MPa)
    • MKS (cm, m, Tn, Kg/cm2)
  • Rich user interface to model the geometry, materials, loads and rebars.
  • Tapered stem (either at toe or heel side).
  • Either Rankine, Coulomb, or Equivalent Fluid soil pressure theories.
  • Multiple loading including surcharge, wind, and seismic.
  • A strip surcharge load can be modeled and wall pressures are calculated.

Calculation results:

  • Check stability forces, shear, and moment diagrams per load combination.
  • Graphic plot moment and shear diagrams to optimize reinforcing bars.
  • Complete stability analysis for overturning, sliding, and bearing.
  • Graphic plot of moment and shear capacity.
  • Graphic display of forces and pressures acting upon the wall.
  • Concrete design of stem, toe, heel, and key.
  • Software finds controlling load combination for each component in bending and in shear.
  • Granular checking of stability and strength by load combination.
  • Water buoyancy effect included.
  • Detailed step-by-step reports with exposed formulas and Code references.
  • Combined text-with-values output message updated with each design change.
  • Outstanding output with Print Preview.
  • Three ways to show the calculations: At-a-Glance, Condensed, and Detailed.
  • Construction sketch generation of retaining wall updated with each change.


  • Project Manager handles calculations and file management.
  • You are in complete control of every single aspect of the design.
  • Design your retaining walls within minutes (not hours).
  • Verify every design step quickly. Not a “black box”.
  • No silly assumptions or math shortcuts. Confident, accurate, and reliable results.
  • Focus your attention on engineering, and let ASDIP RETAIN handle all the mathematical complexity.
  • Multiple calculations stored in a single project file.
  • Safely create, organize, manage, and store your electronic calculations.
