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 greatly simplifies time-consuming calculations in a structural engineering office.


Cantilever Retaining Wall Design
Restrained Retaining Wall Design


  • Simple graphical user-interface to quickly model retaining walls.
  • Complete control of every single aspect of design.
  • Impress clients and plan-checkers with eye-catching reports.
  • Design retaining walls in minutes (not hours).
  • Intuitive wall design using graphical interface.
  • Confidently optimize design and comply with Code provisions.
  • Verify every design step quickly. Not a “black box”.
  • No silly assumption or math shortcut. Reliable, accurate results.
  • Graphic plot moment and shear diagrams to optimize reinforcing bars.
  • Check stability forces, shear, and moment diagrams per load combination.
  • Customize design criteria to achieve a particular need.
  • Any Windows® Operating System. No additional software required.
  • Full compliance with:
    • IBC-12
    • ACI 318-11
    • MSJC-11
  • Complete stability analysis for overturning, sliding, and bearing.
  • Full set of design code load combinations.
  • Specify water table location.
  • 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.
  • Customizable design criteria, options, and conditions.
  • Combined text-with-values output updates with each design change.
  • Three different units systems available:
    • US (in, ft, Kip, ksi)
    • SI (cm, m, N, MPa)
    • MKS (cm, m, Tn, Kg/cm2)
  • Outstanding quality outputs with Print Preview.
  • Multiple calculations under a single project file.
  • Three tabs of results: At-a-Glance, Condensed, and Detailed calculations.
  • Tapered stem (toe or heel).
  • Either Rankine, Coulomb, or Equivalent Fluid theories.
  • Multiple loading including surcharge, wind, and seismic.
  • Software finds controlling load combination for each component in bending and in shear.
  • Graphic generation of structure updated with each design change.

New Features In V. 3

  • Stem material can be concrete, masonry, or combination of both.
  • Step-by-step calculations with formulas exposed.
  • Granular checking of stability and strength by load combination.
  • The restrained walls can be either fixed or pinned at base.
  • A strip surcharge load can be modeled and wall pressures are calculated.
  • Water buoyancy effect included.
