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.

Nonlinear Finite Element Analysis of High Strength Fiber Reinforced Concrete Corbels

This research work presents a nonlinear fini te element
investigation on the behavior of high strength fiber reinforced concrete
corbels. This investigation is carried out in order to get a better
understanding of their behavior throughout the entire loading history.
The three- dimensional 20-node brick elements are used to
model the concrete, while the reinforcing bars are modeled as axial
members embedded within the concrete brick elements. The
compressive behavior of concrete is simulated by an elastic-plastic
work-hardening model followed by a perfectly plastic response,
which terminate at the onset of crushing. In tension, a fixed smeared
crack model has been used.
