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.

[@structuralanalysisanddesign]

Thank you so much for watching, keep supporting

[@shivatribe6297]

Thnx sir explained very nicely

[@superhitragini]

Very well explained sir. But why we are providing cover(60mm) since we dont provided any reinforcement?

[@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

[@manishamudhiraj6825]

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

[@structuralanalysisanddesign]

So nice of you, all the best, main aim is to make student understand in simple manner, keep watching and sharing

[@sheshcharansavakar3536]

Sir please explain the design roof truss problem

[@blazinggamer1581]

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

[@scientificnature]

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

[@structuralanalysisanddesign]

Already uploaded, kindly check it

[@scientificnature]

@@structuralanalysisanddesign not showing sir

[@hri3599]

where did d' come from in the end?

[@siddharthhosmani5993]

Sir could you please upload design of eccentric footing .

[@engineermohammedsoyebbadgu3714]

Please Make videos on Edge footing, Corner Footing with or without Beam on it... And also make a video on Floating Columns or Y Column... Thanks

[@structuralanalysisanddesign]

I will try

[@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

[@harishraj4247]

Sir at last how d' = 60?

[@Pradip1431000]

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

[@vijaybhasker2928]

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

[@structuralanalysisanddesign]

I will be doing it in 2nd part

[@roshanghimire8239]

When will the second part be uploaded

[@structuralanalysisanddesign]

Uploaded, kindly watch the PART 2

[@Leo_Rocky_Rolex]

Sir please make videos on ADVANCED CONCEETE TECHNOLOGY...........there is no proper material available on Google or KZbin so please kindly help with it.

[@structuralanalysisanddesign]

Exactly which topics you want? I will try to do it

[@Leo_Rocky_Rolex]

@@structuralanalysisanddesign sir special concretes , concrete mix design, mineral and chemical admixtures , rheology of concrete, concrete with rice husk Ash, alcofins . It would be very helpful if you could make videos on it 🙂.

[@praneeththeprankboy5887]

Sir you can theory subjects also sir

[@structuralanalysisanddesign]

I dint understood your query

[@praneeththeprankboy5887]

Sir Will you explain theory questions of any theory subject also sir

[@anand4236]

U have not multipled the net upward pressure with 1.5 ...So it's a mistake Any how very elaborated explanation i have ever seen ...Sir please do isolated footing with corner column and edge column and combined trapezoidal footing

[@structuralanalysisanddesign]

Dear, i have multipied factor of safety while calculating moment, kindly watch the complete video. So basically its not a mistake. And i will note your requirements and try to come up with respective videos. Thanks for watching

[@anand4236]

@@structuralanalysisanddesign 👍👍👍👍👍

[@santoshvishwakarma3035]

sir in in net upward pressure total column load is (1450 kn) why are you take (600+800)? you does not take 10% of total weight

[@hemanth2622]

Actually that is wrong, we should take total load which includes self weight also.

[@tellyvella7836]

B=2000MM you took IT IN ONE WAY SHEAR BUT HERE ITS 4×COLUMN SIDE
