Macro fibres have been well accepted for the reinforcement of sprayed concrete in mining and tunnelling applications, and today are starting to be used in other structural elements either in combination with existing steel bars, reducing the size of the steel bars or replacing the steel altogether. Although the use of fibre-reinforced concrete in the building industry is already common practice, generally accepted design methods are still lacking. Due to this many engineers are hesitant to use fibre-reinforced concrete. This paper describes a calculation method for the use of fibre-reinforced concrete for the ultimate limit state (ULS) and serviceability limit state (SLS) using the modification of the latest Austrian guideline - Österreichusche Vereinigung für Beton- und Bautechnik 2008 (OVBB).
