Flexural strengthening

This article presents the experimental results on the flexural behavior of reinforced concrete (RC) beams strengthened with textile-reinforced concrete (TRC). Four RC beams were made of B22.5 grade concrete, and the TRC strengthening layer utilized Sigratex Grid 350 textile, with fine-grained concrete Sikagrout 214-11 serving as the binder.

This paper investigates flexural behavior and analytical approach for predicting the load and deflection at critical performance points of reinforced concrete (RC) beams strengthened with prestressed carbon fiber-reinforced polymer (CFRP) sheets. A finite element model is developed to simulate the interaction between the RC beam and the CFRP sheets, capturing key aspects such as failure modes, ultimate load, and mechanical behavior across the three phases of failure.

In recent years, efforts have been made to produce advanced composite materials in order to lessen environmental impact and to extent sustainability. Traditional materials are largely substituted by composites due to their greater properties like flexural strength, low thermal expansion and high strength.
