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

[@rahmanrahmani2896]

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?

[@rohitmeena6368]

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

[@nidheeshkp9881]

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

[@ayazsiddiqui3263]

Thanks sir...!! 🙏

[@MDHasan-no9vd]

Sir how to calculate Ng?

[@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

[@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!

[@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!

[@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.

[@milan-show-27]

confused how to calculate Area of footing

[@your_study_buddy1999]

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

[@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.
