The advantage of steeped footing
Stepped footing is simple type of isolated footing provide over soil having less bearing capacity. Because low bearing capacity load need to be transfer over larger area and load should transfer with specific pattern (the effective cross section shall be limited by the area above the neutral plane )
The steeped footing are more economical than the steeped ones .

👉Short Notes About Footing
🏷FOOTINGS
➡️Footings are mainly used to transmit the load from super structure to the underlying soil (substructure)
🚧1. Isolated footings
▶️Isolated footings are provided under each column and may be rectangular, square or circular in plan.
▶️It’s footing may be flat or tapered
🚧2. Combined Footings
▶️Combined footing supports two or sometimes three columns in a row.
▶️Combined footing is used when property lines, equipment locations, column spacing or other considerations limit the footing clearance at the column location Combined footing can be rectangular in shape if both the columns carry equal loads or Trapezoidal if there is a space limitation and they carry unequal loads.
🚧3. Strap footings
▶️Consists of two individual footings connected by a beam called strap.
▶️It’s used where the distance between the columns is so great that a trapezoidal combined footing becomes quite narrow, with resulting high bending moments.
▶️The strap beam doesn’t remain in contact with soil so a strap doesn’t transfer any pressure to the soil.
🚧4. Mat or raft foundation
▶️Is Combined footing that covers the entire area beneath a structure and supports all the columns.
▶️Foundation Engineers often considers mats when dealing with any one of the following conditions
*⃣The structural loads are so high or the soil conditions so poor that spread footings would be exceptionally large
*⃣The soil is very erratic and prone to excessive differential settlement.
*⃣The structural loads are erratic and thus increase the likelihood of excessive differential settlement.
🚧5. Pile foundations
▶️Pile foundations are the part of a structure used to carry and transfer the load of the structure to the bearing ground located at some depth below ground surface.
▶️The main components of the foundation are the pile cap and the piles.
▶️Piles are relatively long and slender members used to transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock having a higher bearing capacity.
