Design of Combined Rectangular Footing | PART 1 | | Check for Punching Shear or 2 Way Shear

This video explains in depth the design of Combined Rectangular Footing, this is the 1st part of the 2 parts. 2 columns have to be given a combined footing, two columns are spaced at 3.8m and Column B is heavier than column A. Initially the problem will be analyzed and than proceed with the design calculations. The area is calculated of the footing and than the size of the footing is fixed appropriately, the dimensions of the projections after the columns are shown in detail. Net upward pressure is calculated using weight and SBC of the soil and converted into pressure per meter. To have the uniform pressure distribution the center of gravity (CG) of Columns should coincide with the CG of footing and therefore X is calculated. Shear force and Bending moments calculations are shown in depth, four shear force values will be critical and shear force crosses the zero mark and at that point the bending moment will be maximum (hogging), bending moments and column A and B are calculated and the depth of footing is calculated based on maximum moment calculated. The two way shear or punching shear is checked for the heavier column and it satisfies and safe in punching shear and therefore the depth calculated with respect to maximum moment is adequate.

[@meditatewithmusic5290]

sir,you are very exceptional one thank you for bringing this amazing video

[@studybuddy6642]

This particular video is Very helpful

[@kundhaganesh9920]

Superb explanation i didn't seen this elaborate explanation tq sir.

[@shivatribe6297]

Thnx sir explained very nicely

[@manishamudhiraj6825]

Tq so much sir your vedios hepls the student alot sir.

[@superhitragini]

Very well explained sir.

[@tirruchavan]

TQ u sir❤️❤️

[@satishk2603]

sir can you make a video of combined footing with axial forces and moments P/A +/- M/Z example.

[@mslearningengineering]

Well sir

[@scientificnature]

Please also upload videos on slab design for both one way and two way slab with detailing sir

[@engineermohammedsoyebbadgu3714]

Please Make videos on Edge footing, Corner Footing with or without Beam on it...

[@blazinggamer1581]

Please check, you didn't include the 10% from the concrete weight in the net upward pressure step.

[@sheshcharansavakar3536]

Sir please explain the design roof truss problem

[@siddharthhosmani5993]

Sir could you please upload design of eccentric footing .

[@Pradip1431000]

Make video for combined footing of 300x500 and 500x500 column sizes

[@hri3599]

where did d' come from in the end?

[@hr.builds1914]

Sir you tell us , right side take downward force positive but you take negative in case 538.786 - 800 but there will be + 800

[@vijaybhasker2928]

excellent sir! but sir, can i please know why one way shear was not checked. please sir ....?

[@harishraj4247]

Sir at last how d' = 60?
