Preliminary rectangular shallow-foundation analysis with biaxial eccentricity, tensionless contact, uplift, bearing capacity, sliding and elastic settlement from user-defined limits.

Preliminary analysis of a rigid rectangular footing. The form uses engineering display units while the calculation engine remains SI-canonical.
Mz is not supported and is not editable; no torsional foundation model is applied.
X follows B and Y follows L. For full contact q=N/A+My·x/Iy+Mx·y/Ix. Partial contact solves one coupled biaxial no-tension plane q=max(0,a+b·x+c·y) over an exact clipped polygon.
All capacities, factors and limits are explicit user inputs. Missing checks remain not evaluated; no code compliance is inferred.
Preliminary rigid-footing screening only. The model excludes automatic EN 1997/National Annex partial factors, layered or nonlinear soil, consolidation and secondary settlement, differential settlement, global stability, adjacent-foundation interaction, dynamic loading and structural reinforced-concrete footing design. User inputs and applicability require engineering verification.
