Inelastic analyses using advanced constitutive models are expected to clarify failure mechanisms of piping structures under excessive seismic loading. A multilayer kinematic hardening model for cyclic plasticity is presented for carbon steel pipe, with a set of standard stress-strain properties. The model can express the nonlinearity of stress-strain relations as well as cyclic hardening of the material. Finite element large deformation elastic-plastic analyses with this model are conducted for the JSME piping benchmark problems.
