Abstract
The adoption of innovative, advanced materials has encountered a great growth in these last years, particularly for the civil engineering, in the strengthening field. Aim of the paper is the definition of an “optimal” fiber reinforced concrete (FRC), able to provide an adequate ductility to structural elements. On the basis of available constitutive laws, suitably modified, the relationship between concrete matrix strength and volume fiber ratio is evaluated, in order to obtain a ductile FRC material, characterised by limited softening, or better by a plastic behaviour and higher value of the ultimate strain. The evaluation of the strength and ductility characteristics of these FRC materials is performed by adopting analytical and numerical models, validated by experimental testsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
