Using appropriate material properties for analyzing different models in academic and commercially availablefinite element software is one of the main concerns for design engineers and researchers. This paper demonstrates theimportance of using appropriate material properties for the models to be considered by engineers during finite elementmodelling. Two reinforced concrete (RC) beams strengthened with Carbon Fiber Reinforced Polymer (CFRP) strips areinvestigated, considering the CFRP elements as elastically isotropic and orthotropic materials. To show the significance ofthe selective material properties, all properties of the models are chosen to be exactly the same for the two beams except forthe CFRP strip. To validate the study, an RC beam is tested experimentally and the numerical results are compared to theexperimental test. The results show that CFRP with isotropic or orthotropic properties has no significant influence on beamresponses such as stresses, displacements and damage response under applied loadings.
