New special finite elements for modeling reinforcement and steel‐concrete interface
Abstract
In this paper, Isoparametric finite element formulations are derived for special elements for representing the steel‐concrete interface. Curved multi‐noded Isoparametric element for reinforcing steel idealization is proposed. In addition, special thin Isoparametric element in a form of a sheath is suggested in order to model the bond‐slip characteristics. Special provisions are taken into account to avoid numerical difficulties. The proposed elements are incorporated in non‐linear finite element program DMGPLSTS and applied to the problem of tension stiffening of reinforced concrete members. The results are noted to reflect a softer overall response attributable to the slip effect.
