4. Cantilever or Strap Footing. Strap footings are similar to combined footings. The reasons for considering or choosing strap footing are identical to the combined one. In strap footing, the foundation under the columns is built individually and connected by a strap beam. Generally, when the edge of the footing cannot be extended beyond the ...
