Behavior of corbels strengthened with carbon fiber reinforced polymers (CFRP)‎-numerical study

Abstract EN

In this paper, a numerical modeling performed to study the effect of carbon fiber reinforced polymers (CFRP) as a shear strengthening of corbels.

In this study a theoretical simulation is achieved with reinforced concrete corbels, several CFRP strengthening positions has been studied with different shear span – effective depth ratio (a/d) of (0.

5, 0.

6& 0.

7).

The numerical model, by using program (ANSYS 12.

1) verified by compare its results with the experimental results.

It was found that the position and the amount of (CFRP) as well as the vary of (a/d) ratio, have a great effects on the ultimate load capacity of corbels.

Where, the ultimate load capacity increase as the amount of (CFRP) increased in certain positions of corbels, with regards the vary in (a / d) ratio.
