Comparison of numerical behaviors of FRP reinforced concrete beams using three smeared crack models
Abstract The numerical behaviors of fiber reinforced polymer (FRP) bar reinforced concrete beams using three non-linear finite element models are compared with the recorded data. First approach is based on strain decomposition into elastic and crack strain and is capable of simulating multiple non-orthogonal cracks. The remaining two approaches are based on the total strain crack model and include a rotating crack model (RCM) and an orthogonal fixed crack model (FCM). The analysis is carried out with the help of 2D-isoparametric plane-stress elements. Compression softening and tension stiffening effects of cracked concrete are considered. Tension reinforcement consists of either steel or FRP bars. The accuracy of the models has been discussed with reference to the authors’ tests as well as various studies reported in the literature. Both RCM and orthogonal FCM models showed good agreement with the recorded data which was also found consistent with every type of FRP bar.
