Great videos mate. Just thought I'd mention that for downwards loads, AS 2870-2011 G5.3 states that "No side adhesion or friction should be assumed to exist to a depth of 0.75Hs for down loads" which I believe is to account for the depth of the cracked zone.
Hi Elliot, you're correct. Hs is the depth of design soil suction change and it's also dependent on the climate, So this value change from city to city. I personally don't take the side adhesion into consideration for short piles (residential) design. Thanks for your input
Hi Gabriel(?) I found your channel by searching for building guides in Qld Aus. I am renovating my old Miner's cottage and doing a crash course in construction/building. I am not a builder or engineer but your explanations are giving me a greater understanding of what I need to know in order to understand this process. Watching and rewatching all your videos and really learning, thanks so much
Thanks Lesley. Glad the videos have been helpful to you. Renovating a cottage myself would be a challenge with my limited carpentry skills. Good luck with the project.
Great videos, I have watched almost all of them. Can you make another video or refer me to another text or video explaining the design of reinforcement for piles in residential use? Engineers generally add reinforcement when the pile depths are greater than 1.5m-2.0m but I would like to be able to quantify this.
Do they ever use cris- cross piles in addition to vertical to prevent leaning/ tilting? Or at a 30⁰ angle around outer perimeters in addition to vertical in center?
BEng - fixed support at the top of a pile would induce M1 and V*. By ignoring e=1.5D at the top of the pile, so technically the total moment (M*) would be = M1 + M2 where M2 = V*1.5D ........eg M* = M1+V*x1.5D?
How come builders just pour them into the soil without having a vapour barrier as they do with the slab and footings? I thought moisture from the ground can damage the concrete and it will lose its structural integrity
The vapour barrier prevents moisture rising through the soil and getting into the house. We are not concerned about that when it comes to concrete piers. See the footings for bridges under water. Bear in mind that if the pier is reinforced, adequate cover must be maintained to protect the steel.
well explained! Enjoyed it
Thanks :)
This guy Engineers! More please!
so well explained, all the important stuff and very informative, thankyou
Thanks Clare. Appreciate the feedback
Amazing content! Really helpful for young engineers starting out in the field!
Glad it was helpful! Thanks for watching :)
Thank you Gabriel! Great video and super helpful :)

Hi James, thanks for the support. I will do a video on that. Yeah usually minimum reo will suffice for resi projects.
i will highly appreciate if you could give us a video on Reinforced concrete design of piles in different design methods
great idea.. Thanks for the suggestion
Boa irmão!
Vídeos sempre interessantes. Keep up!
Valeu pelo apoio Ian. Grande abraco

Are you referring to minimum eccentricity? I usually design for the greater of both values.
