MC2010: overview on the shear provisions for FRC
No full textAlthough the use of Fibre Reinforced Concrete (FRC) for structural applications is continuously increasing, it is still limited with respect to its potentials mainly due to the lack of International Building Codes for FRC structural elements. The New Model Code includes several innovations and addresses, among other topics, new materials for structural design, including FRC. The material requirements and design aspects for FRC structures were prepared by Technical Groups fib TG 8.3 “ Fibre reinforced concrete” and TG 8.6 “Ultra high performance fibre reinforced concrete”. This paper aims to briefly explain the main concepts behind the structural rules for shear design of FRC elements

Fibre reinforced concrete: new design perspectives
No full textAlthough the use of Fibre Reinforced Concrete (FRC) for structural applications is continuously increasing, it is still limited with respect to its potentials, mainly due to the lack of International Building Codes for FRC structural elements. Within fib (Féderation Internationale du Béton), the Special Activity Group 5 is preparing a New fib Model Code that aims to update the previous CEB-FIP Model Code 90, published in 1993, that can be considered as the reference document for Eurocode 2. The New Model Code includes several innovations and addresses among other topics, new materials for structural design. In this respect, FRC will be introduced. The Technical Groups fib TG 8.3 “Fibre reinforced concrete” and fib TG 8.6 “Ultra high performance FRC” are preparing some sections of the New Model Code, including regular and high performance FRC. This paper aims to briefly explain the main concepts behind the structural rules for FRC structural design
Calcestruzzo fibrorinforzato nel nuovo codice modello fib
No full textL’uso di calcestruzzo fibrorinforzato (FRC) per applicazioni strutturali è significativamente incrementato negli ultimi anni, ma la mancanza di Codici Internazionali per le Costruzioni limita ancora il suo utilizzo.
All’interno del fib (Fédération Internationale du Béton), lo Special Activity Group 5 sta preparando il Nuovo Codice Modello fib che affronta, fra gli altri argomenti, nuovi materiali per il progetto strutturale, incluso il calcestruzzo fibrorinforzato.
Il fib Task Groups TG 8.3 “Fiber reinforced concrete” e il TG 8.6 “Ultra high performance fiber reinforced concrete” stanno preparando due capitoli del Nuovo Codice Modello, uno sul comportamento del materiale ed uno sul comportamento strutturale.
Lo scopo di questo articolo è di spiegare brevemente i principali concetti che stanno alla base della progettazione strutturale di elementi in FRC, contenuti in questi due capitol
