CSI SAFE - 04 Define Soil Subgrade Modulas (Allowable bearing pressure and settlement)
For Soil Subgrade Modulus
Soil Subgrade Modulus = K= Pressure/deformation
Pressure= Allowable bearing pressure
Deformation = Allowable settlement in the foundation
For example
Allowable Bearing pressure is 200 kPa and allowable settlement is 25 mm.
The Soil Subgrade modulus will be
K= 200/((25)/1000)=8000 kN/m^3 or 8000 kPa/m
**CHECKS
Pressure under footing less than 200 kPa (OK)
Deformation under footing less than 25 mm (OK)
Punching Shear Check less than 1 (OK)
[Preferable should be less than 0.9]
Tips-
If you are failing in any check, go towards for the change in..….. the inputs….. …like change geometry (Length, width and thickness of the footing) and material property etc.
Note:
Allowable settlement for Isolated Footing = 25 mm
Allowable settlement for MAT/RAFT = 50 mm

Hi Welcome It is Casio FX , You can also download, link Is given in the description of the video kzread.info/dash/bejne/nKqjzLJvdMWfqaQ.html
Is all of your course according to the aci standard ?
Dear sir, may I ask what is the reference of allowable settlement you mention above?

These values are almost same in every book... You can check any book on foundation design
please provide the book reference of the calculation procedure of Soil Subgrade Modulus = K= Pressure/deformation

@@chinyerefemi3598 yes you can also use that soon i will upload video regarding Modulus of Subgrade Reaction..... Discussion ... i will clear that doubt.
Sir is that udemy videos by civil mdm
Sir kindly design 20 story building from a to z using etabs aci codes with foundation
Sir, is it okay that maximum soil pressure is positive? If not, how to reduce the soil pressure?
