Description
The study aims to analyze the creep relaxation of concrete cylinder with embedded CFRP bar. A standard pull out test is modelled and time-dependent behavior of concrete is taken into account in a visco-elastic analysis using the creep laws given in Eurocode 2. The CFRP bar are prestressed and decrease in prestressed is simulation alongside its evolution. The stress state reproduced inside the concrete and its evolution correctly matched with the various experimental studies found in the literature. From the result it is concluded that the due to slip restriction greater stiffness is found in the unloading step as compared to the loading step
