Spring Support Generation in STAAD.Pro
Spring Support Generation in STAAD.Pro
(OP)
I am checking a mat foundation that was modeled in STAAD using springs. The engineer used the PLATE MAT feature in STAAD where it "multiplies the subgrade modulus by the influence area of each support node to determine the spring stiffness". I can see how the influence area may be calculated but how do I verify the subgrade modulus for the soil?

Failing that do a load test on soil.

Good luck.

Lufti is on the mark - the geotechnical engineer should be providing those values - and if the structure is "significant", you should work together to iteratively improve them. You see, there is no such thing as "the" k-value - it is a numerical convenience, not an intrinsic property.
