GEOTECHNICAL ANALYSIS & STRUCTURAL DESIGN OF CANTILEVER & RESTRAINED RETAINING WALLS – Ver. 2-IBC 2012/CBC 2013.
SoilStructure Cantilever Retaining Wall (CRW) is one of the most practical retaining wall design software in the U.S. It currently uses only the English unit system at this time. CRW also uses the requirements of ACI 318-11 and IBC 2012. When you have 3 site retaining wall sections to design and it is 4 PM, CRW will get you out of the office by 5 PM.

When you have a retaining wall project to design, you have a collection of checks to satisfy. Some of these checks are stability like sliding and overturning. Other checks are per ACI 318-11, like minimum reinforcement, shear and moment capacity. However, a multitude of geotechnical checks are also needed. These include settlement, wall deflection and global rotational stability. They also include reducing Kp for sloping ground in front of the retaining wall and increasing Ko in the backfill zone for overconsolidated soils. Yet, will still need to do more geotechnical analysis. Since we are using Rankine method, cohesion is allowed in the passive zone. If you are embedded in cohesive soils, why not take advantage of some cohesional strength?. You can combine friction and cohesion beneath the footing base & passive and cohesion in the footing embedment region.
SoilStructure Retaining Wall Design Software considers the soil effects in retaining wall design.
This program is the only retaining wall design software that combines geotechnical checks and structural design calculations as one complete treatment of design. This is the only rational way to design restrained and cantilever retaining walls.
- 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 global stability of passive soils if the materials are cohesive
- 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
- 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
- Reinforcement for Base Shear Keyway
- Shear & Moment Design for Concrete Stem(s)
- Applied force at the top of restrained wall
- 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. Just enough details to document your design.
SoilStructure Retaining Wall V2.0 references ACI 318-11, ACI 530-11, IBC 2012 and CBC 2013 codes plus several international geotechnical publications. Option is given to use friction angle & soil unit weight or the equivalent fluid pressure. We encourage the users to pick 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. Users are assumed to be skilled in the “manual design” of retaining walls.
We fix the stem at the base and pin it at the top for the restrained wall check. 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.
