Tangential plasticity effect on buckling behavior of a thin wall pier under cyclic loading condition

Abstract

The present work aims to investigate the response of thin wall pier subjected to non-proportional cyclic loading. An innovative procedure, inside a return mapping formulation for an unconventional plasticity model, has been taken into account to consider the effect of the tangential stress rate for the generation of irreversible contributions. The new numerical algorithm has been compared against experimental data to prove the reliability and validity of the procedure.
