Abstract/Summary Geotechnical structures usually undergo cyclic loading during its lifetime of service. Bridge piers, abutments are very susceptible to cyclic loading. It has been a long standing problem to solve the cyclic loading phenomena by a reasonably accurate cyclic model. In this paper, a novel cyclic model is developed by extending the one-dimensional Masing’s rule to general stress-space (3D). The cyclic behaviour is simulated by introducing a new framework in which the origin of the stress-strain space is shifted to the instantaneous stress point while the direction of the loading is reversed. A hyperbolic growth function for isotropic strain hardening is used and Rowe’s stress-dilatancy is implemented for the material with slight modification for cyclic loading. No new concept for hardening is introduced here, but the old isotropic hardening rule is applied in an efficient manner to simulate the behavior of material under cyclic loading.
