How to determine the pile capacity. 

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.

Expensive information. Thank yoU!

Nice video. You can't miss even a word said

Great video guys! This info is great material and very useful 👍 Please can you do a video on Loft conversions

Another fantastic video! Thank you! Have you thought of doing any videos on home extensions? It would be a huge help 😁

Very informative video

Tremendous video

Thanks for your sharing! if you can make the next VDO about Pile spring & Soil spring calculation is good.

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.

Amazing video!

Thank you!, I need to know pls what is the conversion between Q all in compression case to Qall in Tension case?

Nice

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

This is applicable for piles dia less than 600 mm. What about large piles with dia more than 600 mm?

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?

y u dont divide the shaft area by 4 as you done in pile surface area

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?

May I know how to obain based bearing capacity and skin friction capacity？

How can you help I have two questions?

Great video. Can you please clarify the reason for dividing the "area of base" by 4?

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
