    Most commonly, they use reinforced pile. For e.g., Bandra Worli sea link. The foundations for the BWSL's cable-stayed bridges consist of 120 reinforced concrete piles of 2,000 mm (6.6 ft) diameter. Those for the viaducts consist of 484 piles of 1,500 mm (4.9 ft).

These 604 piles were driven between 6m and 34m into the substrata in geotechnical conditions that varied from highly weathered volcanic material to massive high strength rocks.

    Strap Footing :- Strap footing is necessitated when a certain column footing has to be restricted in width due to unavoidable interference or boundary limitation. Basically, it is a type of combined footing, consisting of one additional, or more full width column footings connected by a concrete beam.

    Differential settlement in foundation:

    Usually, due to poor compaction, lower bearing capacity of the soil, high depth of hard strata, various changes in water content in soil are the basic reason behind the differential settlement of soil.

    Apart from that, trees & vegetation is not good for foundation safety.

    Soil consolidation is the main reason for differential settlement of the foundation.

    Foundation push piers & foundation underpinning also harms the foundation, which leads to a differential settlement.

    Thank you.

If we have two spread footing foundation (Isolated Pads) of square sizes (1m x 1m) and (2m x 2m),with axial loads ; (10t) and (40t) respectively, by assuming the soil features and specification for the two pads ,is the same , So ...

    Since the dimentions and magnitude of the 2nd is more than the first one, the settlement would not be same roughly. Bcoz the dimension are twice the 1st one, Magnitude is 4 times the 1st one. So bcoz of this, obviously the 2nd footing will be settled more.

    universal foundation is pile foundation.

    it is used at all location, so we call it universal foundation in simple way

    basically pile foundation use at

    • where bearing capacity of soil is low
    • where chances of differential settlement of foundation
    • where structural load is very high like bridge or skyskiper building
    • where black cotton soil is present
    • where bearing strata depth is very high
    • where structure need to resist excessive vibration (wind mill)
    • pile foundation we can use every where.

    What is the Possibility of Footing Failure with Reduced Cement Content?

    Effect of cement content on strength of footing:

    The result reveals that the strength of concrete Foundation increases with increasing cement content in it.

    However, for concrete with cement content more than 150 kg per metre cube then the strength increases with the increase in the size of coarse aggregate up to 25 mm and decreases as the aggregate size increases beyond 25mm.

    Without a proper range of cement in the mixture then low strength development or excessive shrinkage may occur leading to premature deterioration.

    Thank you.

    < strong>contact pressure is the pressure between footing end and soil strata where we rest the footing.

    we should have safe contact pressure to avoid foundation failure like (punching failure, shear failure, excessive settlement of the foundation, etc. )

     

    it is express by load per area

    it is depending on

    • elastic property of soil
    • type of foundation either flexible or rigid
    • type of soil and its various property

    see the figure to more understanding

    Depending on the structural needs one can choose shallow, deep as well as mat foundation. The thing that matters is which type of structure is going to be built. Thank you!
