Finite element analysis of strengthened reinforced concrete beams

Abstract EN

This paper presented the application of nonlinear finite element models in the analysis of rectangular reinforced concrete beams strengthened with ferrocement in the form of U-jacket by using ANSYS software.

The numerical results are compared with the corresponding experimental results of unstrengthened beams.

The comparisons are carried out in terms of load- deflection curves at mid-span, and failure loads.

The predicted results of reference beam are found to be in good agreement with the experimental results.

Effect of number of layers of wire mesh on the strength of analyzed beams strengthened with ferrocement jackets has been studied.

The same beam is also analyzed after strengtheing it with U-jacket sheets of Carbone Fiber reinforced Polymer (CFRB) and the predicted results are compared with that of the corresponding beams strengthened with ferrocement jackets.

The strengthened beams have shown a remarkable improvement in their performances in terms of load deflection and ultimate load.

The Carbone Fiber Polymer U-jacket greatly improved the beam ultimate failure load by about 37.44%.
