Soil Bearing Capacity Analysis Design Template
A Soil Bearing Capacity Analysis Design Template is a standardized, structured framework—typically in spreadsheet, CAD, or BIM format—that guides engineers through the systematic calculation and documentation of a soil's ability to support structural loads without excessive settlement or shear failure. It integrates geotechnical data, loading conditions, safety factors, and regulatory criteria to produce verifiable, auditable bearing capacity assessments. The template ensures consistency, traceability, and compliance with design standards such as Eurocode 7, ASCE 7, or ASTM D1194.

📐 Key Formulas
Terzaghi's Ultimate Bearing Capacity (Strip Footing, General Shear)
q_u = cN_c + qN_q + 0.5γBN_γ
Calculates the ultimate bearing capacity for a continuous (strip) footing under general shear failure conditions, where c is cohesion, q is overburden pressure, γ is unit weight, B is footing width, and N_c, N_q, N_γ are dimensionless bearing capacity factors dependent on φ.
Meyerhof's Shape Correction Factors
s_c = 1 + (N_q/N_c)(B/L), s_q = s_γ = 1 + 0.1K_p(B/L)
Adjusts Terzaghi/Vesic base capacity for rectangular footings using footing aspect ratio (B/L) and passive earth pressure coefficient K_p to account for shape effects.
Allowable Bearing Pressure
q_all = q_u / FS
Derives the design allowable pressure by dividing ultimate bearing capacity q_u by a prescribed factor of safety (FS), typically 2.5–3.0 for ultimate limit state and higher for serviceability.
