Combined and Strap Footing Calculator
Two columns on one base, or a column at the boundary tied back by a strap beam: SANS 10100-1, BS 8110-1, Eurocode 2 or SANS 51992-1-1. The base sized for uniform soil pressure, bending along and across, shear, punching, the strap and its pads, and a bending schedule.
SANS 10100-1 4.10, 4.6 · BS 8110-1 3.11 · EN 1992-1-1 6.1, 6.2, 6.4 · SANS 10160-1 loads · rigid base, linear soil pressure
