Finite element analysis of flexural cracking behavior of RC structures, strengthened by externally bonded CFRP

FE simulation of damage and crack initiation and propagation in RC structure, externally strengthened by CFRP will be presented. Constitutive law, based on the model of Mazars is used for the simulation of the non-linear concrete behavior. In the proposed incremental procedure the regions, affected by damage will be remeshed at each step and the initial mesh will be refined. Numerical results will be compared with experimental results obtained by CFRP strengthened RC beam subjected to a bending
