- Abstract
The nonlinear mechanical responses of concrete beams with carbon fiber-reinforced composite (CFRP) tendons were studied with the finite element model constructed within the nonlinear mechanics theory. The two typical prestressed CFRP-reinforced concrete beams were subject to nonlinear analysis, the stress behavior of the tendons was investigated, the latter and common steels were compared. Experimental data and calculated results are in good agreement. The cracking, yielding, and crushing characteristics of concrete can be well described with the smeared crack model via the Owen yielding criterion and the Hinton crushing criterion. The prestressed CFRP tendons are accurately simulated with combined nonlinear elements, and the corresponding analytical procedure was quite reliable. The CFRP tendons exhibit high strength, retaining their properties even when beam specimens are damaged. In comparison with common steels acting in the tension zone, the CFRP tendons are still in the elastic deformation region during the whole process.
