- Subgrade Modulus (different approaches) | Eng-Tips
Hello, I am working on the geotechnical investigation for a 25 story tower project After computing the stimated elastic settlements (using sigma - W) (project is located on a weathered limestone), I computed the subgrade modulus Subgrade modulus K = applied load elastic settlement
- Modulus of Subgrade Reaction | Eng-Tips
Can anyone suggest ways of accurately estimating the Modulus of Subgrade Reaction for a soil Available parameters: SPT N values, Moisture, Unconfined Compressive Strength Angle of Internal Friction
- Lateral Loaded Piles - Modulus of Horizontal Subgrade Reaction
For slabs on grade, the modulus of vertical subgrade reaction needs to be decreased for increasing slab dimensions Even though the basic theory is the same, slabs on grade and laterally loaded piles are treated differently, and you have to keep this in mind when looking at the subgrade reaction parameters
- Modulus of Subgrade Reaction (k) | Eng-Tips
The modulus of subgrade reaction is a basis for structural engineers to evaluate deformation from point loads that may or may not be applied to the slab Say, you know a racking system will be installed in the completed building The rack load may be applied anywhere in the building, so the structural engineer needs to account for these point
- Subgrade Preparation | Eng-Tips
We are constructing a 10" gravel roadway over existing surface No cutting of existing ground will occur Is it normal to run a roller over the existing ground and get our 95% compaction before placement of the rock?
- Soil Subgrade Modulus K Value ????? | Eng-Tips
I am designing a raft slab foundation on grade for a G+1 light gauge steel hospital building in SAFE software The soil bearing capacity is 50 KN m2 and soil is soft clay soil but to analyze this foundation in SAFE I need to know the subgrade modulus “K” value so any one can suggest the
- Approximate relationship between allowable soil bearing pressure and . . .
To me, this means there IS some relationship between allowable bearing pressure and subgrade modulus Geotechnical engineers typically limit the allowable bearing pressure to the pressure which causes 1 2" settlement
- Is subgrade modulus still used by structural engineers?
Even mat foundations can be designed without subgrade modulus Just to be clear, I know subgrade modulus is still used for pavement and sometimes slab-on-grade designs However, I've got a structural engineer client who is asking for the subgrade modulus to design a footing
