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