Shallow Foundation: Numerical on Calculation of Safe Bearing Capacity and Permissible Load

This video discribe the procedure of calculation of Safe Bearing Capacity of Shallow foundation and Permissible Load that can be carried by a footing. We have used Terzaghi's Method for calculating safe bearing Capacity
Terzaghi’s method is, in fact, an extension and improved modification of Pandtl’s (Terzaghi,1943). Terzaghi considered the base of the footing to be rough, which is nearer facts, and that it is located at a depth Df below the ground surface (Df ≤ b, where b is the width of the footing).

Normally the BCS (Bearing Capacity of Soil) is determined by soil investigation on site through boreholes. This value has to be divide FOS = 2 or 2.5 ! Thank You!

[@sambhavtakkamore6081]

What is the ultimate bearing capacity of a circular footing of 1 m diameter resting on the surface of a saturated clay of unconfined compression strength of 100 kN/m2? What is the safe value if the factor of safety is 3?

[@nidheeshkp9881]

Please can you tell me how can we calculate bearing capacity using N values (SPT)

[@ceo31122]

Excuse me Sir
Here this is Local Shear Failure
Phi < 26 ° so we have to assume it local shear failure
For that
Cm = 2/3 × C is to be considered but u have taken here directly C how can it be possible ??
Please reply sir 🙏🙏

[@CuriousCivilEngineer]

It was not mentioned in the statement but ur right

[@048-ritikkumar9]

haan ye wrong hai

[@ayazsiddiqui3263]

Thanks sir...!! 🙏

[@rohitmeena6368]

sir please tell how calculate depth correction factor asper IS 8009 for SBC asper SPT

[@wruwan]

Thanks

[@CuriousCivilEngineer]

Your welcome Ruwan

[@alial-araji222]

Why are you adding gamma x Df and calculating qsafe? Why can’t you just use qns? Thanks

[@CuriousCivilEngineer]

Because in the numerical it was asked to determine q safe not the net safe bearing capacity.

[@alial-araji222]

Thank you!

[@rahmanrahmani2896]

Could please NOT mark the calculation with a red marker or erase it after marking that the viewers can take a clean shot of the calls for future reference! Thank you!

[@milankarkee]

confused how to calculate Area of footing

[@MDHasan-no9vd]

Sir how to calculate Ng?

[@TRAVELAIRDROP]

very tanckfull

[@nasirmanzoor3425]

how to calculate ultimate and allowable load

[@CuriousCivilEngineer]

Divide the SBC with Area of the footing.

[@parthasarathi2767]

Once again to tell how to compute the value of length of footing

[@CuriousCivilEngineer]

For calculating bearing capacity, length of the footing is assumed as 1 meters. It is not calculated. If you're asking about design of the footing, the length comes from loading and flexural requirements.

[@your_study_buddy1999]

It is local shear ,,,c should be 13.33 times

[@chandrashekar5933]

Sir can upload pdf

[@ninjamele1925]

Do we need the bc factors or memorise the values?!!

[@CuriousCivilEngineer]

Factors are available along with code. If codes are not allowed in the exam then you will need to remember them.

[@ninjamele1925]

@@CuriousCivilEngineer but how?? there are so many values....any short trick to memorise it

[@CuriousCivilEngineer]

Sorry no other way. You just have to practice a lot.

[@ninjamele1925]

Thankyou for replying anyways sir....next rime i will practice....tomorrow i will just leave the question if by chance it is asked cuz i cant memorise the bc factors at one night....thanking you sir😘😘😘😘😘😘

[@CuriousCivilEngineer]

Sure best of luck.
