Meyerhof’s approaches: The important difference between Terzaghi’s and Meyerhof’s approaches is that the latter considers the shearing resistance of the soil above the base of the foundation, while the former ignores it. Thus, Meyerhof allows the failure zones to extend up to the ground surface (Meyerhof, 1951)
Skempton proposed equations for bearing capacity of footings founded in purely cohesive soils based on extensive investigations (Skempton, 1951). He found that the factor Nc is a function of the depth of foundation and also of its shape.
Brinch Hansen (1961) has proposed the following semi-empirical equation for the bearing capacity of a footing, as a generalization of the Terzaghi equation. It has been found that Hansen’s theory gives a better correlation for cohesive soils than the Terzaghi theory, although it may not give good results for cohesionless soils.
Vesics bearing capacity formula
22:08 Small correction in depth factor of IS Code method. I forgot under
root Nphi in dc dq formula. Please refer pdf for corrected formula.
Link in description for PDF
20:11 should there be q(Nq-1)??
Thanks you the corrections. Will look into it.
sir, in pdf Dq and Dy formula is wrong because Nphi will be multiplied in second term only and not in whole term so please do correct it.
@@sanishbhochhibhoya7750 actually in IS code directly Q net ultimate is given, that's why q(Nq-1)is used but here formula is for Q ultimate (Qu) only so -1 is omitted
the best explanation anyone can give, hats off to you.
The best I could come across
Excellent video.
Thank you
V informative video buddy 😎
Please make playlist of videos according to chapters..
Great going 👍
Sir can you explain local and general shear failure clearly please
Which software u r using for delivery of lecture
Power Point, for capturing screen of laptop I am using OBS. For audio video editing Audacity and Openshot. Watch this video drive.google.com/open?id=1LvMyhDm0kqWvk3hp6tmG-YY-GeIg4Bl5
Jazakallah
Can i use hansen and vesic eqs in case of vertical load, horizontal ground condition
Vesic is good too
sir muze bearing capacity sai foundation ki dimension nikalni hai... fir Df, b, alpha kaise consider karna... IS code kai method mai
How do i find bearing capacity using prakash and sarans theory? Are there graphs available?
Please refer the book "Principles of Foundation Engineering" by Braja M. Das. In case you don't have that book, use thia pdf link for the this theory. Link : drive.google.com/file/d/1CL2J2rzV4BxgK9_mURjc_4fubl1v1DIC/view?usp=drivesdk
Let me know if you find what you looking for.
sir what software do you use for recording?
This is done on MS power point.
Please make a video on is code numerical with all type water table factor
Yeah great Idea... will upload it tomorrow.

Which method is the best for calculating bearing capacity, please your opinion sir
I think its IS Code method if ur using Indian standard and if you're from other country then use Meyerhof's method.
Thanks sir
In my mini thesis
I used Meyerhof, hansen, vesic eqs to calculate bearing capacity.
But idk which eq is more safe
Can i use avg value of these eqs
How you think sir
You can compare the results for all of them. Take some footing of rectangular shape and calculate the factor of safety. The method which gives higher FoS is safer.
Thank you for you kindly reply What value of Fos should be used in these eqs?
You have to calculate FoS by assuming size of the footing.
Sir vesic Ka sum ni samajra h inclination vala part kuch tarika batado
which part ? please text me on my WhatsApp
@@CuriousCivilEngineer ok sir
لماذا الفيديو لايحتوي على الترجمة الى اللغة العربية
I don't understand what it says bit I am guessing it's a positive thing
