| Abstrakt: |
The classical approach considering perfect bond between steel rebars and concrete is often unsuitable in refined analysis of reinforced concrete elements, as it leads to significant errors in the estimate of the actual stiffness. For this reason more refined procedures have to be considered. In the paper a numerical algorithm is illustrated, able to predict both the evolution of the crack pattern and the crack widths during the whole loading process, based on a refined local bond-slip law, derived from ad hoc tests. |
