The book moves from some general concepts which drove the development of the research in the project. First of all fibre reinforced composite is considered as a unique material in terms of mechanical characterization: some alternative approaches, partly described in the material chapters, have to be regarded as qualitative approaches which can give to the designer, who is interested in the material optimization, a rough idea of possible tools to improve specific material properties or even to understand some peculiarities or anomalous behaviour quantitatively measured in the experimental tests. The book concerns with fibre contents lower than 1% and therefore the uniaxial tensile behaviour is always softening: the stress vs. crack opening relation in uniaxial tension is considered the basic constitutive law.

Abstract
The book moves from some general concepts which drove the development of the research in the project. First of all fibre reinforced composite is considered as a unique material in terms of mechanical characterization: some alternative approaches, partly described in the material chapters, have to be regarded as qualitative approaches which can give to the designer, who is interested in the material optimization, a rough idea of possible tools to improve specific material properties or even to understand some peculiarities or anomalous behaviour quantitatively measured in the experimental tests. The book concerns with fibre contents lower than 1% and therefore the uniaxial tensile behaviour is always softening: the stress vs. crack opening relation in uniaxial tension is considered the basic constitutive law. It can be identified by uniaxial tension tests or easier by bending tests, by using suitable relations able to relate bending behaviour to uniaxial tension. The research report can be roughly divided in two main folds: the material properties and the structural applications. The results have been gathered in order to facilitate the reader, starting from the former issue and moving towards the latter, passing from the crucial point of the generalized constitutive laws which relate the two worlds, trying to emphasize all the aspects that reveal as key points for the designer. The book represents an attempt to force the authors to a real discussion on the results obtained in the MIUR project and to spread as much as possible the knowledge acquired in the research investigation. The publication is addressed to a structural engineer interested in the understanding of which possibilities are offered by Fibre Reinforced Concrete use in Civil Engineering and in a better comprehension of the limitations introduced in the CNR DT-204 recommendations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
