Abstract:

In the past, two distinctly different approaches - smeared and discrete failure models have been adopted to describe failure mechanisms in plain and reinforced concrete structures. Although many fundamental issues remain to be resolved before a unified approach towards failure processes will emerge we may safely conclude: (i) the smeared failure approach is suited best to describe progressive cracking in RFCS up to the formation of a localized failure mechanism, and (ii) the discrete failure approach is suited best to describe the progression of discrete failure mechanisms in the post-peak regime. In that way, the two methods do complement rather than compete with each other in response regimes for which they were not conceived originally.
