Modeling of reinforced concrete by the non-local microplane model Original Research Article

This paper reviews some recent results of non-local finite element fracture analysis of concrete structures using a non-local microplane material model. The microplane model and recently introduced non-local microcrack interaction approach are described briefly. It is demonstrated that the model used in smeared fracture finite element analysis does not exhibit mesh sensitivity. Results of a three-dimensional numerical study of fastening elements pulled out from cracked and uncracked reinforced concrete plates are shown. The capability of the model for correct prediction of the structural size effect is supported by one numerical example. In all examples numerical results are compared with experimental evidence and reasonably good agreement is observed.
