It is difficult to use the traditional equi-linearized method to evaluate the earthquake response of the weak-ground, because in such method the frequency-dependence of shear modulus and damping is impossible to be considered. In this paper, the fading memory theory has been used to study equi-linearized method with frequency-depended shear modulus and damping. Frequency-depended equi-linearized method has been presented and the influence of the characteristics of fading memory function on the interaction between nonlinear ground and foundation has been discussed in detail. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
