The study of cyclic behavior of such bars has an important role in the assessment of seismic vulnerability of existing RC structures. The detailed analysis of experimental outcomes obtained by an extensive experimental campaign on smooth steel bars with different L/D ratios (L is the stirrups spacing and D is the longitudinal bar diameter) represents the focus of this paper. The cyclic damage and buckling in compression depend on such ratio, and they strongly influence the hysteretic response of smooth steel bars in terms of stress-strain relationship. The analyzed ratios have ranged between 5 and 100 in order to take into account all the real configurations within the joint zones. In particular, the higher ratios (i.e. 75 or 100) represent the innovative aspect of this study: they are representative of geometrical conditions, in terms of stirrups spacing and longitudinal bars diameter, within RC elements of the years between the ‘60s and ‘70s which are typically characterized by high stirrups spacing.
