Finite element analysis of RC beams strengthened with textile reinforced concrete

Abstract

The paper reports the development of a finite element modeling methodology for the response of reinforced concrete beams strengthened with textile reinforced concrete (TRC). Appropriate material models were integrated to simulate the behaviour of the strengthened beam. A smeared cracking model was used to represent the behavior of TRC. For this, the input data for the tension stiffening model was developed based on tensile characterization test results. The interaction between the various material ingredients was also incorporated in the modeling. Nonlinear finite element analysis was carried out to simulate the response of strengthened beam under flexure, and the results obtained from the analysis are found to be in good agreement with experimental results.
