Cantilever and Restrained Retaining Wall Design Software

RAPID RETAIN – GEOTECHNICAL & STRUCTURAL EFFECTS OF CANTILEVER/RESTRAINED RETAINING WALLS – V3. 

SoilStructure RAPID RETAIN, version 3 is a user friendly rapid retaining wall design software. Our market is USA & portions of Canada that utilizeS the English unit system.  It can analyze cantilever and restrained retaining walls that are comprised of Reinforced Concrete or Concrete Masonry Units.  It can also analyze fence walls.  It currently uses the English unit system. CRW also complies with the requirements of ACI 318-14 and 2012/2015 IBC.  NOTE: There is no yearly maintenance fee, so the USB price you pay is all that you pay! This software was rewritten over a 9 month period until we were satisfied that it is robust yet rapid, thus the RAPID RETAIN name.

When you have a retaining wall to design, you have a collection of checks to satisfy. Some of these checks are stability analysis like sliding and overturning.  Other checks are per ACI 318 like minimum reinforcement, shear and moment capacity. However, a multitude of geotechnical checks are also needed.  These include settlement, wall deflection and stability of a temporary vertical cut.

SoilStructure RAPID RETAIN Software considers the soil effects and the temporary excavation stability of retaining structures.      ( VIEW Retaining Wall Video )

This program is a retaining wall design software that combines geotechnical checks and structural design calculations as one complete treatment of design.

SoilStructure RAPID RETAIN software has the following unique capabilities:

  • Taking into account the response of bearing pressure when axial dead & live loads are present
  • Computation of retaining wall footing settlement due to distortion & consolidation settlement
  • Checking for stability of excavation cut
  • Sizing stem walls for Wind
  • Design of shear stem key @ the top of footing – bottom of stem interface
  • Calculation to check of whether Active or At rest or in between earth pressures apply to the stem
  • Calculating passive earth resistance when passive soils are descending, ascending or level
  • Calculating at rest earth pressure when the backfill soils are overconsolidated and inclined
  • Option to include all 3 common surcharges – point load, line load and strip load
  • Creating P-M interaction diagram for each stem wall section
  • T & S Bars analysis and detailing diagram
  • Development, splice length & detailing is automated for the stems, heel, toe and keyway

Medium Height Retaining WallIn addition, the following design checks for a cantilever & restrained retaining wallS are in RAPID RETAIN:

  • Reinforcement for Base Shear Keyway
  • Shear & Moment Design for up to 3 Concrete Stem or CMU stem sections
  • Applied forces and moments at many locations along the stem
  • Shear & Moment Design for Heel Slab
  • Shear & Moment Design for Toe Slab
  • Design of optional footing keyway as a bracket
  • Temperature & Shrinkage for Stem and Footing
  • Inclusion of detailed Tables, Charts, References and Dynamic Diagrams
  • A compact, detailed and color report with reinforcement cross section that is drawn to scale
  • A 7 to 9 page report (depending on surcharges and stem sections) can be printed in PDF or on ink.

SoilStructure RAPID RETAIN V3 references many recent and few obscure but great publications. Option is given to use friction angle & soil unit weight with Rankine, Coulomb or Muller-Breslau or the equivalent fluid pressure.  We encourage the use of friction angle/unit weight option as these are fundamental properties that are measurable in the geotechnical lab.  Three parallel windows are displayed to reveal the effects of your input and output. Users are assumed to be skilled in the “manual design” of retaining walls.

Basement wall design philosophy: We fix the stem at the footing base and pin it at the top for the stem wall. The program will give you the lateral force at the top of the wall. We also suggest you check a cantilever condition of all restrained walls, since the wall may be backfilled early by the contractor. The double curtains of steel will come in handy for restrained wall design.

A word about the Equivalent Earth Pressure (EFP) method to design cantilever & restrained retaining walls. We provide this option because it is in most soils reports. According to Huntington in 1957 (About 60 years ago) said this EFP method should be discontinued. That is because it does not represent ascending backfill slope pressures well.
