Abstract
This paper presents the results of several resonant column tests carried out in a large variety of soils, including lateritic and saprolitic tropical soils. The data analysed are restricted to the strain dependence of shear modulus in the range of 10-6 to 10-2. Despite the different isotropic consolidated stresses, degrees of saturation and overconsolidation ratios applied for the different types of soil, all the test results fit very well in a previous proposed normalised curve of G/G0 as a function of γ/γ0.7, where γ0.7 is the shear strain corresponding to a value of G≈0.7 x G0. The hyperbolic stress-strain equation can conveniently describe this fitting. Simple practical relationships are also proposed for tropical soils to the prediction of G0 and γ0.7 allowing with the normalised curve to estimate shear modulus in the strain range relevant to the service state of many civil engineering structures.
