This paper presents a model which are capable of accurately describing the shear stress-strain of horizontally-layered soil deposits subjected to the upward propagating shear waves caused by an earthquake. This model is characterized as the general form of the well-known Hardin-Drnevich modeling on shear stress-strain relation of soils, and therefore can fit the laboratory-tested skelton curve of a soil more accurately than any other model available at present. Moreover, the variation of damping ratio with shear strain evaluated through this model incorporated with the Masing rule is in good agreement with the corresponding laboratory test results. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
