TLDR
In this article, the main concepts behind the structural rules for Fibre Reinforced Concrete structural design are briefly explained, and a New fib Model Code that aims to update the previous CEB-FIP Model Code 90, published in 1993, is presented.Abstract:
Although 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 (Federation Internationale du Beton), 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.read more

Fibre‐reinforced concrete in fib Model Code 2010: principles, models and test validation
TL;DR: In the fib Model Code for Concrete Structures 2010, fiber-reinforced concrete (FRC) is recognized as a new material for structures as discussed by the authors, and the most important constitutive law introduced is the stress-crack opening response in uniaxial tension.

Finite element modeling of crack band propagation
Zdenek P. Baiant,Luigi Cedolin +1 more
TL;DR: In this article, the propagation of blunt smeared crack bands through a finite element mesh in plain or reinforced concrete structures is studied, which is satisfactorily accomplished by extending the previously proposed concept of free bond slip length for the cases of skew meshes and skew bars.
