High performance fiber reinforced concrete for the shear reinforcement: experimental and numerical research
High performance fiber reinforced concrete (HPFRC) is developing rapidly to a modern structural material with unique rheological and mechanical characteristics. Despite applying several methodologies to achieve self15 compacting requirements, some doubts still remain regarding the most convenient strategy for developing a HPFRC. In the present study, an innovative mix design method is proposed for the development of high17 performance concrete reinforced with a relatively high dosage of steel fibers. The material properties of the developed concrete are assessed, and the concrete structural behavior is characterized under compressive, flexural and shear loading. This study better clarifies the significant contribution of fibers for shear resistance of concrete elements. This paper further discusses a FEM-based simulation, aiming to address the possibility of calibrating the constitutive model parameters related to fracture modes I and II. ; The research in this paper is part of the project "DURCOST - Innovation in reinforcing systems for sustainable pre-fabricated structures of higher durability and enhanced structural performance" with reference number of PTDC/ECM/105700/2008, supported by FCT. The authors also thank the collaboration of the following companies: Casais to manufacture the moulds, Ibermetais for supplying the steel fibres, Secil/Unibetao for providing the Cement, BASF for supplying the superplasticizers. The first author acknowledges the research grant in the ambit of this project.
