ACI 318-19
Cantilever Retaining Wall Calculator (ACI 318-19)
AutoDesign’s retaining-wall tool designs reinforced-concrete cantilever retaining walls to ACI 318-19. It covers global stability — overturning, sliding and bearing — and the strength design of the stem, toe and heel, with an optional shear key.
What this calculator does
- ✓Design RC cantilever retaining walls to ACI 318-19
- ✓Stability checks: overturning, sliding and soil bearing
- ✓Strength design of the stem, toe and heel
- ✓Optional shear key to boost sliding resistance
- ✓Active/passive earth pressures, surcharge and water table
Frequently asked questions
Which stability checks are included? +
Factors of safety against overturning and sliding, plus a soil bearing-pressure check (including the resultant eccentricity within the base).
Can I add a shear key? +
Yes. An optional shear key under the base can be added to increase passive sliding resistance, and it is included in both the stability and strength checks.
Does it design the wall reinforcement? +
Yes — the stem, toe and heel are designed for flexure and shear to ACI 318-19 in addition to the global stability checks.
