When the allowable soil pressure is relatively high, and the distance between the columns is considerable, an eccentric footing is more economical than a combined footing. Spread or isolated footing. In designing a strap footing, it is first necessary to proportion the footings. This is done by assuming a uniform soil pressure beneath the footings; that is, R 1 and R 2 (Fig.33) act at the centroid of the footings. Strap (noun) A long, narrow, pliable strip of leather, cloth, or the like. Click Here To See Difference Between Strip Footing And Strap Footing Strap or Cantilever footing: A strap (or cantilever) footing consists of two isolated footings connected with a structural strap or a lever.

The strip footings aren’t poured until the slab is poured. Strip foundation is used to support loads specially in frequent columns. Found inside – Page 289Similarly, strip footings are placed under the walls that carry the line loads. Combined footings or strap footings carry more than one column load. Pile Footing. A cantilever footing is a component of a building’s foundation.

Difference Between Footing and Foundation The following is the comparison of footing vs foundation Footing The main difference between footing and foundation is that footing is part of the foundation, which spread an entire load of foundation to the ground surface. A strap footing is more economical than a combined footing when the allowable soil pressure is relatively high and distance between the columns is large. Strip Footing Raft Foundation. Spread or isolated footing. 2. This type footing is commonly used for the foundations of load bearing walls or supports a slab.
