In order to simulate the ground motion under arbitrary loading including rotation of the principal stress axes, the authors incorporate a proper constitutive equation in dynamic analyses. In the present paper, a parameter is proposed to consider the effect of stress reversal subjected to earthquake loading. The parameter is substituted in the Matsuoka's constitutive model (1986) that can evaluate the yield due to rotation of the principal stress axes. Simulations of simple shear tests, shaking table tests and liquefaction analysis of irregular grounds are carried out. Those numerical studies indicate that Matsuoka's model can be applied to the seismic response analysis of the ground under the arbitrary loading.
