- Abstract
- In this paper a tension stiffening model based on the bond-slip relationship is introduced and adopted in a finite multi-layered
shell element formulation for surface structure analysis. The tension stiffening effect evaluated at the meso-level is taken into
account in the constitutive law of reinforcement for the macro-level by defining a crack element at the Gauss point. The crack
element is iteratively analyzed by means of a step-by-step integration, which allows application of any complicated bond laws.
To define the crack element, a crack spacing model considers the crack formation grade. As a relevant factor in this tension
stiffening concept, the reinforcement cracking stress may be evaluated by taking the fractile value of the concrete tensile
strength. Through several simulations, the validity of the concept is systematically investigated under monotonic and cyclic
loading. The analysis under cyclic loading shows the effect of the re-contact of the crack flanks. The numerical examples
demonstrate the applicability of the applied reinforced concrete model with a tension stiffening effect.
