Secondary Compression Calculator

Calculate long-term creep settlement: S_s = C_αH·log(t₂/t₁). Secondary compression index C_α: peats 0.05-0.15, organic clay 0.02-0.06, inorganic clay 0.004-0.015. Important for organic soils and embankments on peat.

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 to Use

Enter the values for the patient or scenario you are assessing. Calculate long-term creep settlement: S_s = C_αH·log(t₂/t₁). Secondary compression index C_α: peats 0.05-0.15, organic clay 0.02-0.06, inorganic clay 0.004-0.015. Important for organic soils and embankments on peat. Use the secondary compression result to inform your clinical assessment.
