ASDIP Structural Software announces the release of ASDIP RETAIN 5 engineering software. Design professionals utilize ASDIP RETAIN software for the design of retaining walls. The following are some of the most important features and benefits included in this version 5.

This new version includes four modules:

  • Cantilever Retaining Wall Design – The stem material can be either concrete or masonry. The program accepts a number of load cases, such as surcharge (strap, uniform and/or concentrated), wind, and seismic. Graphical results. Construction images with the rebars
  • Counterfort Retaining Wall Design – Easy modeling and interpretation of results. Multiple load types and load cases. Results sorted by load combination. Either soil supported or pile supported. Lateral pressures are calculated either per Rankine, Coulomb, or Equivalent Fluid theories.
  • Basement Retaining Wall Design – Up to two-stories can be modeled. Multiple load types and load cases. Either pinned or fixed base. Graphical generation of the shear, and moment diagrams. Multiple options to customize the design. Excellent quality pre-formatted reports of condensed and detailed calculations.
  • Sheet Pile Retaining Wall Design – Cantilever and anchored types. Up to four layers of soul properties can be modeled. Graphical generation of the wall pressures, the combined loading diagram, shear, moment, and deflection diagrams. Immediate calculation of embedment depth.

In addition to a better layout design and dozens of improvements, the following are the most important new features and benefits in ASDIP RETAIN 5:

ASDIP RETAIN 5 New Features

Code Compliance

 ASDIP RETAIN 5 complies with ACI 318-14 and 19, AISC 360-16, AASHTO LRFD-20. Load combinations per ASCE 7-05 or 10/16, or AASHTO.

AASHTO and User-defined Load Combinations

The AASHTO LRFD load combinations have now been implemented in ASDIP RETAIN 5. This new feature is useful to design bridge abutments and other highway retaining structures. The AASHTO Strength load combinations include the maximum and minimum load factors. The structural design of the retaining walls meet the latest design provisions by AASHTO, including the type of loads applicable to the different stability failure modes. The graphical results can be sorted by load combination for granular checking.

Custom load combinations can now be created from scratch. When a new set of load combinations has been created, it can be saved for future use. You can even produce your own library of load combinations and save it for different projects. This is very useful if you need to consider load combinations applicable in another country, or variations of the standard ASCE 7 combinations. 

You can simply select a load combination file previously saved and ASDIP RETAIN will use the user-defined combinations to proceed with the design.


Sorted Results by Load Combinations

The graphical results in ASDIP RETAIN can be sorted by load combination. With this feature the engineer can do a granular check in great detail and find out the results for any load combination, as opposed to get just the "controlling results". This is a very useful and important checking tool during the design process. This feature applies to the standard ASCE 7 or AASHTO combinations, and to the custom load combinations as well.

Once the design has been completed and optimized, the ASDIP RETAIN reports will show the controlling load combination for each limit state and member design.

Sheet Pile Retaining Wall Design

ASDIP RETAIN 5 now includes the design of cantilever and anchored sheet pile retaining walls per the latest CALTRANS Trenching and Shoring Manual. This is a very useful module for the design of excavation and shoring projects. Several layers of soil properties can be modeled, as well as the position of the water table in the area. You can specify a safety factor to affect the passive pressure in the calculation of the embedment depth.

The diagrams of pressures at both sides of the wall, combined loading, shear forces, bending moments, and deflections, are generated immediately as you enter the input data. The software will calculate the required embedment depth, and the maximum shear and moment. With this information it will calculate the required structural properties of the sheet piling. This is a new module requested for a long-time by our customers, and it is now part of ASDIP RETAIN 5.


Improved Detailed Results

ASDIP RETAIN 5 now shows the graphical results in separate tabs for each stability failure mode analysis, such as overturning, eccentricity, sliding, bearing. The previous version showed only one tab for the stability analysis. The graphical results can be followed granularly per load combination, or showing the identified combination that controls the design. This is a very important feature since different external loads should be applied for each stability mode, for example live surcharge should be included for bearing, but not for overturning, etc.

In addition, concentrated horizontal and vertical loads are now included, which is particularly useful in the design of bridge abutments. This will provide the elements to model the reactions of the superstructure. Surcharge and concentrated loads can now be specified as dead and live loads, which allows a better calculation of the combined loads.

 The pre-formatted Condensed and Detailed reports are clean and well organized to present the results professionally.



ASDIP RETAIN 5 includes the the design of several types of retaining walls, compliance to the latest design codes, AASHTO and user-defined load combinations, and a new module for the design of Sheet Piling. The design of such systems may be completed and optimized in minutes, and the results can be checked immediately.

ASDIP Structural Software

  • Do you offer a software module that handles the cantilever of the likes of a small portal leg, where lateral restraint is offered at the concrete floor level and the pile or leg of the portal is in timber or steel as a limited height retaining wall with regular centre distances between regular cantilever column piles that are placed with sheathing between then. These column/pile are placed into an augured larger concrete bored pile base of a greater diameter as a composite section below the ground level that is often tied at the concrete floor. Like wise for smaller portals legs that are only cantilevered below the ground in concrete perhaps with a predetermined fixed end moment at the floor level which is needed to be resisted from the soil below.

    We only deal in metrics, I presume all your softwares works in metrics input and output please respond thank you to the above requirements so we can definitely entertain the purchase of such a package thank you.

    • This sounds too complicated to be answered with a simple yes or no. Please send me a sketch to [email protected] and I will take a look and will tell you my opinion on how to use our software in your case. By the way, our software works in metric units as well. Thank you.
