CEEN 341 - Lecture 25 - Bearing Capacity Part I

[@EhabKaram1984]

Thank you Prof. Franke, i enjoyed your lessons and added much to my knowledge, am following your lessons from Egypt. thanks for your much efforts.

[@edgaraguilar4484]

Congratulations!!. Very useful lessons. Greetings from La Paz in Bolivia!

[@juliolobo7835]

Professor Franke thanks for all your lessons..i already finished your Elementary Soil Mecahnics Class

[@zainabibrahim3002]

Please upload the rest of the couse as soon as possiple ..... thank you for sharing an amazing knowalage with us 🌹

[@alexramosbellido492]

These lectures are amazing. And it is wonderful to know where the formulas you have learnt, come from. Thaaaank you very muchh. Greetings from Peru.

[@christogontarimo7340]

Thank you so much following you from TANZANIA. 👍💪

[@ahmedkamla2109]

Thanks for the video! Great explanation.

looking forward to CEEN542!

Missing your lecture on pile goundations. I am glad I found you.

[@emilybickel9712]

Your videos are amazing! I don't think I would be able to understand the mohr circle if it wasn't for you.

[@JohnEloi]

Thanks for sharing your knownledge!

[@mdcorei1077]

Very good explanation. Thankyou very much sir!

[@gh5030]

Thank you so much for the this great lesson

[@lucanicolaquaroni858]

Thank you for your clear explanations!

[@Neo-qp8iy]

thank you very much for these very nice videos, if you don't mind, could you use the metric units in your calculations for the next lectures.

[@1yoan3]

Yes please, or at least have both. The rest of the world has no idea what psf, feet, psi, pounds... are.

[@rikindehood9003]

Both units are used as international standards. SI units are French-defined to mean notations change in 10 values.

[@nitinsingh3551]

Can you post remaining foundation engineering topics with in this month

[@mhick3333]

Great presentation

[@geneva1202]

Good Job!

[@WordsandNumbers1]

Nice explanation, sir. I have two questions. why is the curve of least resistance exactly a logarithmic spiral? Also, in the diagram for friction stress, the friction stress we are talking about is on the surface of elastic zone, right ? If so then why is it not constant ?

[@officehours4028]

1) difficult question to answer. The shear plane wants to find a path back to the ground surface, but it needs to “turn around”. That path of turning around usually takes the shape of a log spiral. 2) the elastic zone extends across a certain depth of soil. Friction is a linear function of stress (....remember the Mohr-Coulomb failure criterion). Therefore, as depth increases, friction will increase linearly as well.

[@WordsandNumbers1]

@@officehours4028is this friction force is similar to the passive force like in Rankine's theory required to cause failure on the slip surface(curved in this case) ? Or is it just the friction force on the surface of elastic zone due to foundation loading, (analogy to friction on inclined plane due to a simple load resting on the plane)?

[@officehours4028]

The latter.

[@WordsandNumbers1]

@@officehours4028 if so (analogy to vertical load on an inclined plane), then it should be linear as friction is uniformly distributed on the plane, isn't it, sir ?

[@mehulkatakiya4892]

@@WordsandNumbers1 its frictional resistance which is sigma'*phi'..n see..it increases LINEARLY with depth.

[@qaisershahzad408]

I am thankful for a very comprehensive lecture. I have a question, as how can we find the extent/dimensions of zone II and zone III. thanking you in anticipation.

[@mikhailchannel8122]

Absolutely love your videos! Thank you!!! One question at 32min 19sec for case (I) What is Gamma (2) equation? Thank you!

[@TheAncientColossus]

Gamma 2 is the unit weight of the soil within the frictional wedge.

[@christianjun6393]

Where is the ceen 442 :)?.. thanks for ur explanation doc as always

[@silverbackdungeongorilla4315]

thank you old man

[@zinash5mashie993]

Thank you very much , it is so helpful

[@de-leonmindset8468]

Thank you!!!,,,,,Very informative video! 100%

[@atlisurahi]

great lecture, thank you!

[@munavarshaikh5224]

Please do send me the link of CEEN 442.

[@goldonon]

Thank you very much!

[@alicitobalongoy2294]

sir thank you for the knowledge...

[@BrendaAMasso]

Bravo!!!!!!!!!!!!!!!!!!!!!!!

[@nepomokhehle4877]

What textbook should i use for reading soil mechanics?

[@civilengineeringtutor8510]

For Soil mechanics you can use principle of soil Mechanics by Braja M. Das. It's a very good book to understand the basic

[@myke0101]

thank you
