Shallow Foundations
Spread footing bearing capacity, settlement, and sliding — with shape, depth, and load-inclination factors and effective-area reduction for eccentric loads.
Start Free TrialWhat it does
The Shallow Foundations tool sizes and checks spread and strip footings. Bearing capacity is computed by the Vesić general equation with shape, depth, and load-inclination factors and effective-area reduction for eccentric loading, plus a Terzaghi cross-check.
Settlement is evaluated by e-log-p consolidation for cohesive soils and elastic methods for granular soils. Sliding resistance and the applied bearing-pressure distribution round out the checks.
Output is a formatted PDF report with the bearing-capacity build-up, settlement summary, and demand/capacity ratios.
