Moment-curvature model for flexural assessment of textile-reinforced concrete beams

Several numerical models reflecting the flexural response of steel-reinforced concrete beams have been developed in the past. However, their adaption to carbon-reinforced concrete needs to consider a different type of material behaviour. In addition, they must be able to reflect numerous reinforcement layouts with more flexible configurations of textile fabrics within the cross-section. In this paper, a general cross-section model for the derivation of the moment-curvature and load-deflection curves for concrete beams reinforced with short fibers, bar reinforcement and textile fabrics is introduced, which incorporates materials non-linearities and is easily applicable to cross-sections with arbitrary shapes and reinforcement layouts. The validation shows the ability of the model to reliably reproduce the experimental results.
