thank you doctor very much for your time and giving knowledge ... i would like to ask yo sir .. basically am a geologist and am working in geotechnical field .. i like this field and i would like to go for a master in geotechnical engineering .. but geologist are qualify to do this master ?
Hi Dr Kamarudin, I have one question regarding shallow foundations - in New Zealand here when we designing for retaining walls, if Df/B ≤ 1, we say they are shallow foundation. Are the definitions different depends on the locations? Thanks in advance. Great video.
Dr. Kamarudin, berdasarkan Mackintosh / Jkr probe, kita biasa tgk correlation chart utk allowable bearing capacity. Katakan ~50 Blows/0.3m kita boleh adopt qall ~ 130-140kPa BC, tapi bila kita kira menggunakan Mayerhof, kita masuk kan bearing capacity factors Nc,Nq & Ngamma, qall yang kita akan dapat adalah lebih tinggi. Boleh kah kita kekal dgn qall yang kita dapat dari correlation chart itu saja utk design the bearing pressure?
@@kamarudinahmadphd7412 noted tkasih Dr. Kamaruddin. yang mengelirukan saya bila kita design shallow foundation, kita diberikan allowable BC 100kPa, bila kita ada soil shear strength parameters kita akan guna dgn Mayerhof atau Terzaghi dan dimension pad footing kita dah design to exert 100kPa bearing pressure, then qall tuh biasanya lebih tinggi daripada 100kPa tuh, adakah kita overly conservative dgn BC 100kPa yang kita mula2 adopt for design?
A square foundation (B × B) has to be constructed as shown in figure. Assume γ = 1 15 lb/ft3 and Yal = 121 lb/ft, depth of foundation (Dr) 4 ft and depth of water table (D) 1.5 ft. The total load on the column is 400 kips. The standard penetration test results are shown below. The tests were conducted using US style donut hammer in a 6" diameter boring with standard sampler. th (ft) N-(blow/ft) 10 15 20 25 10 Use Factor of safety- 3, calculate the size of the footing using Terzaghi's bearing capacity equation. Assume general shear failure Water soil BXB Hint: Depth-wise N value is given. Calculate depth-wise N and (Nio and use correlation to calculate friction angle '). You need friction angle to estimate bearing capacity factors
Bearing capacity and its types. A square footing 2.5m by 2.5m is built in a homogenous bed of sand density 2.00 t/m3 and having an angle of shearing 38o. the depth of a base of the footing is 1.5m below the ground surface. Calculate the safe load that can be carried by a footing with a factor of safety 3 against complete share failure. Use Terzaghi ‘s analysis. Solve these also share the book links
Base contact pressure along shallow independent foundation Known: footing dimension 4m×2m, Fk=680kN with eccentricity 1.31m. The buried depth d=2.0m, the unity weight of foundation and filled soil γd= 20kN/m3 . Find out: the maximum contact stress along the spread footing
I would like to express my deepest appreciation for your patience and carefulness in the video! Absolutely phenomenal!
Thank you Sir. I am watching this in Zimbabwe and it's really easy to understand. Thank you
Are you engineering student
Thank you so much for such a clear explanation. Much gratitude from Sri Lanka 🇱🇰🙏🏼
Crystal clear to understand sir. Terima kasih dan semoga Allah membalas jasa Dr mencurah ilmu kepada anak bangsa.
Thanks alott ❤❤ I wish you guys the best luck in the world 🌹🌹🌹🌹
terima kasih tuan.. 20 tahun dulu benak betul nk faham Dr ajor..banyak main kat kelas..huhuhu..
Ngeh3....boleh saya tahu siapa yang komen ni? Tahun bila masuk kelas saya?
You know what, I'm subscribing, cristal clear❤🎉
Thank you Dr. Your presentation and explanation is easy to understand
Many thanks Dr the
explanation is Very clear
it is really good explanation. many thankss
Thank you so much sir.am from uganda
Thank you prof for the explanation. I'm grateful
Great demonstration, much appreciated
Thank You dr, for the explanation.
Thank you, it was really helpful.
This is amazing.
Thank you so much for these videos!!

please make a vedio of soil bearing capacity from spt value
why you use c instead of c' in the formula for square footing?
Thank you , the video is helpful
Salam.. Saya sedang merekabentuk sebuah Jeti Pendaratan Ikan.. Boleh Dr suggest, contoh buku design yg sesuai untuk rujukan. Terima kasih Dr.
Where can I buy this book?
Good job bro well understood 👍👍
is there any example for two way loading ? Thank you
Thank u sir
thanks Dr., can you provide the PDF for the yellow book ??
What if the angle of friction is 0?
thankyou dr!

Sir I don't know how you get NC, Nq, Ny.. I don't know how to get them using table.. Can you plss explain it?
