| Abstract: | The equivalent linear seismic response of a horizontal site is done by the finite element method in this paper.Time interval division of earthquake motions in the effective stress analysis,the variation of modulus with the iteration number in the equivalent linear calculation and the effects of differences of both the frequency spectrum of earthquake motion and the dynamic characteristics of sites on the maximum earthquake shear stress acting soil layers are studied by calculations. |
