Retaining Wall Overturning Calculator

Check overturning stability: FOS_OT = ΣM_restoring/ΣM_overturning ≥ 1.5-2.0. Restoring moment from wall weight and soil surcharge. Overturning moment from active earth pressure resultant. Location of base resultant.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Check overturning stability: FOS_OT = ΣM_restoring/ΣM_overturning ≥ 1.5-2.0. Restoring moment from wall weight and soil surcharge. Overturning moment from active earth pressure resultant. Location of base resultant

Each component has a specific meaning:

  • Wall weight — The wall weight recorded for the patient or scenario being assessed.
  • Soil surcharge — The soil surcharge recorded for the patient or scenario being assessed.

Note: Interpret the retaining wall overturning result against the clinical thresholds and context described above.

How to Use

Enter the wall weight, soil surcharge for the patient or scenario you are assessing. Check overturning stability: FOS_OT = ΣM_restoring/ΣM_overturning ≥ 1.5-2.0. Restoring moment from wall weight and soil surcharge. Overturning moment from active earth pressure resultant. Location of base resultant. Use the retaining wall overturning result to inform your clinical assessment.
