Abstract
In a context of inexorably growing engineering challenges, the search for concomitant achievement of structural safety, economic efficiency and environmental sustainability leads to the development of materials of increasing efficiency. Several studies show Fiber Reinforcement Concrete (FRC) to be a promising material regarding its post-cracking behavior related to the enhanced material toughness. Despite its good performance and broad applicability, the literature still lacks a comprehensive constitutive model to precisely describe its tensile behavior. In this work, a cross-section analysis approach is employed to determine the crack mouth opening displacement in FRC beams, considering the RILEM TC 162-TDF multilinear FRC constitutive model. Results are compared with literature data, and a statistical analysis is carried out, showing the model is an adequate representation regardless of the amount and material of the fibers.
