Bending Moment in Footing | Footing Design | Design of footing | Maximum bending moment in footing

[@CivilEngineeringMastery]

The size of the footing is 2.56 x 2.56m and qu is 343.32 kN/m2. Kindly ignore the calculation error.

Nice explanation

[@HeenaDabasia]

Very Well explained Madam 👏 However I have a question on the Bending moment, A column passes down the axial load on to the foundation from which we calculate the Bending moment on the foundation which in your example it comes to 585 KNm, If the column had an axial load together with a Bending Moment say 'M' do we add this bending moment to 585 KNm and then design the Pad foundation with 585 KNm + 'M' to get the total bending moment on the footing? Or should we ignore the M?

[@rahmanrahmani2896]

Excellent work as always. Could you write all the formulas that you are using for the calcs. You need min reinforcement at the top in both directions as well. Could please do one combined footings with eccentric loadings. Thank you

[@brianmugabi7516]

Minimum reinforcement may not be necessary especially if the ultimate moment is greater than the design moment. Otherwise, it is necessary.

[@rajendrajhoorawat95]

Excellent mam

[@shunmugaraja.k.beatsofhear6775]

Thanks for giving your Knowledge. Please post raft footing for reduce the steel alternative to mat footing.

[@brianmugabi7516]

Well explained especially how the bending moment comes about and why reinforcement steel is provided at the bottom.

Thank you!

Please make video on DESIGN OF DOUBLE ECCENTRIC OR CORNER FOOTING

Very nicely explained, Thank you very much once again. Regards

You're the best Mam

Thanks for sharing valuable knoweledge

[@CivilEngineeringMastery]

Glad it was helpful!

Great

[@ghiovanidayanan2716]

Hello, I would like to ask how do you prepare your presentation, just like that hand writing. How did you do that? thanks

[@frsaj7396]

please make video about shear wall design

[@praveenkumar-tz3in]

Nic👍

Mam also post how to find the depth of a footing and depth of beam

[@narendrarbhagyaa1012]

Mam well explained thank you

[@INDIAmeansBHARAT1950]

Can we find bearing capacity of soil

Mam where to provide double mat in footing and why? Please explain.thank you.

[@solaimanhossain2097]

Hi madam i like your lecture

[@CivilEngineeringMastery]

Thank you! 🙂

[@sudarshannikam5243]

Mam u have calculated Ast for whole section 2650 x 667 mm, But u calculated bar spacing for 1000 mm strip. So at 9:42, There should have 2650mm instead of 1000mm. Actual spacing will be 297 mm for 20 mm dia bar.

[@rakeshtanwar7283]

When you are calculate the size of flooting Area = 6.6 m^2 , side = squre root 6.6 = 2.56 by you can take 2.6 Bymistake you take 2.65 instead of 2.56

[@CivilEngineeringMastery]

Thank you for the notification. The size of the footing is 2.56 x 2.56m and qu is 343.32 kN/m2. Kindly ignore the calculation error. This information was pinned in the comment box.

How the net soil pressure can be greater than SBC?

[@CivilEngineeringMastery]

Net soil pressure is calculated at ultimate load. Factor of safety - 1.5

[@jawaharbharani1866]

Can the soil resist more pressure than SBC,how?pls explain.

[@CivilEngineeringMastery]

No need to compare Net soil pressure at ultimate load with SBC. Actual soil pressure should not exceed SBC. Actual soil pressure q = (load/area)+Self weight of footing + Self weight of soil.

[@kapishsharma1018]

@ 5:10 in area of footing calculation why you have multiply 1500 with 1.1 and from where it came

[@CivilEngineeringMastery]

1.1 is 10% of back fill load. (1500X1.1) is the total load or 1500+((1500X10)/100).

[@narasimhamurthy2800]

Mam I think the area of footing will be 2.56*2.56 then the area will be nearly 6.6m2 please check once.

[@CivilEngineeringMastery]

Yes, you are correct.There was a error.Thank you for the notification.

[@rajeshkumarlohana]

Bending moment is not calculated properly,

[@MKapitan]

Double check the calculations tho Just two major errors within a few seconds Footing sides = SQRT(6.6) is NOT 2.65 qu is not 320.4 I think she fell on the calculator or something....

[@CivilEngineeringMastery]

Kindly ignore the calculation error. look into the concept.
