MODIFIED SKELETON CURVE IN SOIL STRESS-STRAIN RELATIONSHIP FOR IRREGULAR CYCLIC LOADINGS

In this paper, a new concept of a 'Modified Skeleton Curve' is presented to replace the common skeleton, curve in one-dimensional soil stress-train relationship given by Masing rules. Based on the 'Modified Skeleton Curve' a simple and convenient empirical functional form of one-dimensional soil stress-strain relationship under irregular cyclic loadings is advised for use.
