Step-by-Step Benchmark Walkthrough
- Define Design Boundary Conditions: Establish the nominal operating parameters for the component or system:
Pile Diameter D (mm) = 800, Embedded Depth L (m) = 14, Undrained Shear Strength cu (kPa) = 65, Pile Head Fixity = Free Head (Independent Pile / Light Cap). Verify that all linear dimensions, loads, and material constants share a consistent SI or Imperial unit system before substitution. - Execute Analytical Formulation: Substitute the normalized input vector into the governing relation (
H_u = 9 · c_u · D · (L - 1.5D) • H_allow = H_u / FS (Broms Method for Cohesive Soils / FHWA GEC 012)) in accordance with Eurocode 7 (EN 1997-1 Geotechnical Design), FHWA Geotechnical Engineering Circulars, ASTM D1557 / D2487, AASHTO Green Book (Geometric Design of Highways). - Verify Computed Engineering Outputs: For the baseline design case, the calculator yields
Allowable Lateral Working Load = 2396.2 kN; Ultimate Lateral Soil Resistance (Hu) = 5990.4 kN; Ineffective Upper Zone Depth (1.5D) = 1.20 m; Assumed Geotechnical Factor of Safety = 2.5 FS. Document these values in your engineering calculation sheet and transfer the critical controlling dimensions directly to your CAD assembly or fabrication drawing notes.
