Granular soils can amplify earthquake shaking at small strains without reaching the level of pore pressure generation. The hysteretic constitutive behaviour of sands and gravels under this specific consideration has been described in the thesis using the total stress based simplified model, SimSoil (Pestana and Salvati, 2006). SimSoil retains the basic features of the hysteretic constitutive behaviour described in the generalized effective stress model, MIT-S1 (Pestana 1994). It uses only four parameters (n, Gb, ws, and wa) which are readily determined from laboratory tests. Model parameters in the SimSoil execute independent control of nonlinearity of the soil behaviour under cyclic loading which is a unique feature of this model. ...
