Abstract: Combined with the extended Masing's rules, the dynamic constitutive re lationship is employed to evaluate the nonlinear hysteretic property of soil mat erial under transient or cyclic loadings. Incremental method and the general solution to linear seismic response of layered foundations with exponential function shear modulus are synthesized to develop a seimi-analytic calculating technique for nonlinear dynamic problem, and a nonlinear analysis procedure is presente dand numerically implemented to simulate seismic response of this sort of found ations. A practical example is analyzed to confirm the validity.
