Soil shear modulus typical values
Webresponse analysis, and soil structure interaction. The shear modulus (G) of soils is highly re-liant upon strain level. The small-strain shear modulus (G. max) is typically linked with strains on the order of 10 3 % or less [1]. With knowledge of G. max, the shear response at various le-vels of strain can be estimated using modulus reduction (G ... WebApr 12, 2024 · E s is soil elastic modulus; R f is the soil failure ratio, with typical value of R f = 0.75~1.0; and ε 50 is the strain corresponding to one half of the maximum principal stress difference. The soil rigidity factor is 200~500 in the collected database, which covers the range for the typical clay suggested by USACE [ 41 ].
