Good day Mr Structural Engineer Calc. I have this problem that i am solving and i can not find any relevant to the question, Please assist me with any source of relevant material that i can use to get it solved or any method or steps that i can follow to get to the correct possible design. Provide an optimal design of a 16 m long concrete pile that is to be driven into 12 m of loose sand that was underlain by very stiff clay. The geotechnical parameters of the sand and stiff clay are respectively as shown in Figure Q2 below: Sand: ∅’= 26°; Unit weight γ = 19 kN/m3 Stiff clay: cu = 80 kN/m2; Unit weight γ = 18 kN/m3 The pile is expected to undertake the following characteristic loads: DL = 35 00 kN LL = 25 00 kN Also, Fcu = 40 MPa and Fy = 450MPa Additionally, maximum pile length allowable = 20 m (meaning the stiff clay can extend to 20 m depth). The idea behind this exercise is to provide an optimum design.
Thank you very much for the awesome videos. I was wondering if you could make a video on determining the depth of piles under lateral loads using Brom's method, or any other method you think works. Cheers.
Thank you for the kind words! We appreciate your support and are glad that you enjoyed the video. We'll continue to work hard to produce high-quality content for our viewers. Thank you for watching!
This is good, easy to understand. Just a question, don't we need to multiply by 2 when calculating Area of pile base and Area of frictional surface for pile considering that 2 piles are supporting the Column?
I get that the two piles share half the load but don't we need to consider the distribution or "load spread" based on the angle of the lines drawn in the pile cap?

Your presentation are flawless and your videos are very informative.
Nice video. You can't miss even a word said

Provide an optimal design of a 16 m long concrete pile that is to be driven into 12 m of loose
sand that was underlain by very stiff clay. The geotechnical parameters of the sand and stiff clay
are respectively as shown in Figure Q2 below:
Sand: ∅’= 26°; Unit weight γ = 19 kN/m3
Stiff clay: cu = 80 kN/m2; Unit weight γ = 18 kN/m3
The pile is expected to undertake the following characteristic loads:
DL = 35 00 kN
LL = 25 00 kN
Also, Fcu = 40 MPa and Fy = 450MPa
Additionally, maximum pile length allowable = 20 m (meaning the stiff clay can extend to 20 m depth).

great video sir. Appreciate your knowledge sharing.
Expensive information. Thank yoU!
Kindly explain in a video about how to determine pile length, pile moments and design.
Erhm ,can you please do a video on the design of concrete pedestal for steel columns. Thanks
Thank you!, I need to know pls what is the conversion between Q all in compression case to Qall in Tension case?
Great video guys!
This info is great material and very useful 👍
Please can you do a video on Loft conversions
Thanks for your sharing! if you can make the next VDO about Pile spring & Soil spring calculation is good.
Very informative video
Tremendous video

Amazing video!

Another fantastic video! Thank you!
Have you thought of doing any videos on home extensions? It would be a huge help 😁
This is good, easy to understand. Just a question, don't we need to multiply by 2 when calculating Area of pile base and Area of frictional surface for pile considering that 2 piles are supporting the Column?
No you don't need to multiply by 2 because we already divided the column load by 2.
Great video. Can you please clarify the reason for dividing the "area of base" by 4?
It is a constant that you use to get area of circle when you use diameter in stead of Radis, I think
Area or circle, pi * squared D / 4
I get that the two piles share half the load but don't we need to consider the distribution or "load spread" based on the angle of the lines drawn in the pile cap?
No you don't need to!
This is applicable for piles dia less than 600 mm. What about large piles with dia more than 600 mm?
May I know how to obain based bearing capacity and skin friction capacity？
y u dont divide the shaft area by 4
as you done in pile surface area
How can you help I have two questions?
Nice
also to calculate shaft surface area y u took pile length 5.5m
Pile cap design show
Self weight of pile neglected
Analytical methods for piles are quiet old and not convenient
