The Ultimate Design Tool for Segmental Retaining Walls

AB Walls is a comprehensive design tool which outputs professional quality construction drawings with technical support data. It allows designers to transfer a conceptual layout from a site plan to a complete wall solution and then export it to various CAD software programs. In addition, designers can generate elevations, plans, and multiple cross sectional views of their retaining wall projects.

Some of the program’s design capabilities include static and seismic calculations for internal, external and internal compound stability. AB Walls can take a designed wall project and print a complete package in one step making it an easy submittal to your client.

Inspired by the work on the Best Practices for SRW Design document to help drive the industry towards zero wall failures, many changes and enhancements have been included in the our latest version.

What Else Can AB Walls Design Software Do?

Detailing Enhancements:

AB Walls Design Software

One of the most difficult parts of the design and build process for segmental walls is conveying the design requirements to the contractor. AB Walls has greatly enhanced the Submittal and Shop Drawing Outputs to allow the designer to:

  • Fully detail the wall profile with specific stationing and elevations of all step ups and step downs on the top and bottom of the wall profile.
  • Provide multiple cross sections along the profile to thoroughly detail the design variations that can occur along the length of the wall.
  • Display site specific wall drainage details directly on the cross sections. Blanket drains, chimney drains, drainage swales, etc. can now be shown directly on the cross section.
  • Fully detail the plan view with stationing and geogrid depths. Knowing the geogrid depth allows the designers and contractors to avoid possible grid obstructions during construction.
  • Provide individual panel views connected directly to their design panel section to provide clarity for grid placement.

Design Enhancements:

  • A designer can now model up to three different soil layers for both the infill and retained soil layers. This multiple soil layer modeling is used in the Internal Compound Stability section of AB Walls.
  • Use Trial Wedge Design Methodology for slopes above the wall in seismic regions. This provides the designer an alternative to the traditionally used Mononobe Okabe (M-O) method that greatly limits the steepness of slopes above any seismically loaded wall.
  • An engineer can see graphical results from the Internal Compound Stability analysis from the Pressure Mapping page.
  • Offers Internal Compound Stability analysis to be applied to No-Fines Concrete designs. Recently completed independent testing has provided a conservative design friction angle which allows the designers to utilize the benefits of ICS calculations on No-Fines Concrete sections as well as geogrid applications.
  • Provides complete design flexibility as each panel calculation is independent so the user can design with geogrid in one panel and No-Fines Concrete in the next panel, each having their own independent loading conditions.

Output Enhancements:

AB Walls still provides both a Submittal Output for the engineers to submit for design review and a detailed Shop Drawing Output for use in the field - but now even better!

  • Both packages include all detailing enhancements listed above. However the Submittal Output provides safety factor information for:
    • Internal Calculations
    • External Calculations
    • Bearing Calculations
    • Static and Seismic Loading
    • Internal Compound Stability Calculations
    • Internal Compound Stability Pressure Mapping
  • Designers can choose from 33 typical details to be printed in both outputs.
  • All design information in the Shop Drawing Output can be exported to .DXF format for use in any CAD program. Included are the Profile View, Plan View, Sections and Panel View, General Notes, Specifications and Specific Section Notes.

ReSSA Export:

Allan Block has worked closely with the designers of ReSSA, the industry leading global stability analysis program, to allow the section information from AB Walls to be exported to a ReSSA file. This gives the wall designer the opportunity to easily transfer information from AB Walls to ReSSA to investigate the global stability of the project site quickly and efficiently.

Tutorials:

The Allan Block Engineering Dept. offers basic and advanced tutorials on the use of AB Walls. Tutorials are offered to individual engineers or can be done in a group setting to cover your firm’s engineers at once. These tutorials take less than 60 minutes to provide the designer with industry information and functionality of the program to begin designing retaining walls. Completed tutorials are then eligible for continuing education credits (CEU’s).
