Shear modulus - Earthquake Engineering - Northern Architecture

Apr 11, 2021  Shear modulus. For soils the stress-strain behaviour of most interest in earthquakes is that involving shear, and, except for competent rock, engineering soils behave in a markedly non-linear fashion in the stress range of interest. For small strains the shear modulus of a soil can be taken as the mean slope of the stress-strain curve.
