What is a Strap Footing

A strap footing is part of a building’s foundation. It is a sort of combined footing, along with two or more column footings connected by a concrete beam. This kind of beam is called a strap beam. It helps distribute a load of either closely or eccentrically loaded column footings to adjoining footings.

strap footing is often used alongside columns, which are located along with a construction’s property or lot line.

Typically, columns are centered on column footings; however, in conditions where columns are placed directly adjacent to the property line, the column footings can be offset so they do not encroach onto the adjoining property.

It therefore results in an eccentric load on the footing part, causing it to tilt to one facet. The strap beam restrains the tendency of the footing to overturn by connecting it to nearby footings.

Strap Footing

When a beam relates the independent footings of columns, it is referred to as a strap footing.

It is used while the space between the columns is adequate that a combined trapezoidal footing becomes relatively slender, with high bending moments. In this case, the column is provided with its independent footings, and a beam is used to connect the two footings.

The strap beam doesn’t remain in contact with soil and thus doesn’t transfer any soil strain. The strap assumed to be infinitely stiff transfers the column load at the soil with the same and uniform soil strain underneath each footing.
