In the current study, a new approach to represent the carbon fiber reinforced polymer (CFRP) fan type anchors in finite element analysis is produced. That method is based on increasing the bonding strength between CFRP and concrete over a specific area where the CFRP anchor penetrates the concrete. It was implemented by using new bond-slip model to represent the interface between CFRP strip and concrete over a specific area where the CFRP anchors penetrate the concrete; the parameters of the proposed bond-slip model are related to the parameters of the unanchored bond-slip model proposed by Lu et al. Eng Struct. 2005;27:920-937. These parameters were estimated by fitting of the finite element analysis results to available experimental results from the literature published by one of the authors. The results obtained by using the proposed model showed a good agreement with those from experimental results.
