NON-LINEAR ANALYSIS OF PLATED T-SUBJECTED TO NEGATIVE BENDING MOMENT

Abstract

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