In engineering a foundation is an a improtant part of the structure which transfers the load of the super structure for the foundation soil.Fotting are the important part of foundation for the construction purpose and they are also typically made by the concrete with reinforcement.The footing which contact with groung level is called footing

what are the types of footings

  • Isolated footing
  • Combined footing
  • Strap footing
  • Raft or mat footing
  • Flat footing
  • Stepped footing
  • Sloped footing

    • Isolated footing

    In isolated footing the footing are provided under the earth column separtly are called isolated footing. Isolated footing are may be in square,shape, rectangular and circular.In this comprise of a thick slab which are flate or steeped.

    what is footing

    Combined footing

    In combined footing support are tow or more columns.combined footing may be in rectangular or trapezoidal shape the footing are provided when isolated footing of adjacent column overlap each footing 

    what is footing

    Strap footing

    strap footing is also a one type of footing and it consist of isolated footing for two column connected by rhe beam is called strap footing 

    what is footing

    Raft or mat footing

    where rhe columns are having or the safe bearing capacity of soil is very low and the required footing area become very large.A raft footing is an a solid reinforcemt concrete slab covering hollow area benath the structure and supporting of the all columns  

    what is footing
                                                                      Flat footing: Flat footing are generally in circular, rectangular and square shape and it is provided in under each column independently.It is in the circular and rectangular of uniformly thickness.

    Stepped footing:
    Stepped footing are generally used in olden days now they are outdated.Flat footing are also called as a stepped foundation.Stepped fitting are made easily and it is in the foundation part.

    Sloped footing:
    Sloped footing are generally in the shape of trapezoidal.The sloped footing generally strong and strength.When the compared trapezoidal footing with a flat footing the usage of concrete is less.

    What are the advantages of footing

  • The shallow fundation if required Little excavation
  • If can be designe accommodate sites
  • Economic control of foundation
  • Easy to construct
  • Tension and reinforcement shear can be added
  • It can be complete less time only to construct

    • What are the disadvantages of footing

  • The foundation size is very large with a high point
  • it is very weak in uplift forces
  • It has requried deep excuavtion for foundation
  • Weak aganist the settle ment that may effect the what are the types of footing.
