👏 👏 👏 this channel just keeps on giving and giving. Appreciate you guys giving your spare time doing these tutorials makes the engineering world so much easier thank you secalcs 😃
I am very happy that I have watched your RUclips videos (you are the most comprehension and so kindness for the world and me.too.)I never studied live loads and dead load of buildings at university but when I will build a small house. I must know some information that connecting the best way for building it from RUclips.Thanks your videos.bye.... goodbye...,
What about from elevation zero we have -0.5 m concrete, followed by a -1.5 m soil instead of 2m soil from elevation zero? What will be the shape of the pressure on the wall due to concrete and soil.
guys i am a little confused here also by the units given when calculating the max resultant pressure at the base of the wall.. its expressed as 13.2kN/m but dont think this is correct as its ka of 0.33 which is obv unitless x soil density 20kN/m^3 x 2m which should result in a unit of kN/m^2.. but he does say "13.2kN per m per m run" so presumably this gets you your m^2? Just a little confusing for anyone trying to learn the basics as we all know getting the correct unit output is so important with all of these things
what is Q?, the lateral pressure or resultant lateral pressure force?. Lateral pressure due to surcharge = 20*0.33. Resultant lateral pressure force=Lateral Pressure * area= 0.33*20*H*1= KN acting at the centre of the pressure diagram.
You have made me understand so clearly my today's Geotechnics class..
Abundant blessings to you.

This is a truly great channel

Surcharge pressure that acts laterally is Ka x Q. SO it has to be multiplied by 0.33
I was going to comment the same thing. Glad you picked it up
Another Great Vid - I see you have incorporated the buy a coffee! Well done, and about time. Sending you 3 coffee's now 😀☕☕☕
An amazing channel. Thank you so much.
Great video. Kindly make a video on how to design abutments and retaining walls constructed in stone masonry.
Great channel
Do load sets 1 & 2 get added together?
What about from elevation zero we have -0.5 m concrete, followed by a -1.5 m soil instead of 2m soil from elevation zero? What will be the shape of the pressure on the wall due to concrete and soil.
How can we get surcharge load
Perfect, go ahead by applying the load for multistory buildings
In Set 2, you need to calculate unfactored lateral pressures based on reduced soils strength parameters.
Hi, greetings please do some video on pier design & abutment & return wall design
great job
FE Manual has P=1/2 x unit weight x Ka x H^2. How come you didn't square the height (2 meters) in this example?
Has h valued already included in 13.2 kN/m which is Pa so Resultant P= 1/2*Pa*h ( here 1/2* base* height where Pa= 0.33*20*2)
Water pressure a big issue.
Improper drainage and frost heave causes failure .
Also Angle of repose varies with soil type.

correct
The total surcharge Q must be multiplied by 0.33
agreed
OP should pin this
Agreed
Correct
Correct yes
Is there scope for structural engineering yet?
How do we determine the surcharge of 10Kn sq/m
I think it is given
the surcharge part is incorrect.
I think that Q=20x0.33=.....
iyaa, as though the surcharge pushes laterally into the wall according to the video
what is Q?, the lateral pressure or resultant lateral pressure force?. Lateral pressure due to surcharge = 20*0.33. Resultant lateral pressure force=Lateral Pressure * area= 0.33*20*H*1= KN acting at the centre of the pressure diagram.
Q=ka*q*H
