ABSTRUCT:- This paper present a numerical analysis using ANSYS finite element
program to simulate the reinforced concrete T- beams strengthened with external bonded
steel plates when subjected to negative bending. Eight beams with length 2.0m and simply
supported were modeled. Nonlinear materials behavior, as it relates to steel reinforcing bars
and plain concrete, and linear behavior for plate is simulated using appropriate constitutive
models. The results showed that the general behavior of the finite element models represented
by the load-deflection curves at midspanappear well agreement with the test data from the
previous researches. Also the crack patterns at the final loads from the finite models are
discussed . The finite element models represented by this search can be used to carry out
parametric study for the strengthening of plated T-beams.
