Commentary on the DAfStb Guideline "Steel Fibre Reinforced Concrete"

The Guideline was adapted to the new standards for concrete construction in 2012. Thus Part 1 of the Guideline was revised on the basis of DIN EN 1992-1-1 in conjunction with DIN EN 1992-1-1/NA. While DIN EN 206-1 and DIN 1045-2, published in 2001 and 2008 respectively, continued to form the basis of concrete technology, a new European Standard for the execution of concrete structures, DIN EN 13670, was published in 2011 and now applies in conjunction with the revised, March 2012 edition of DIN 1045-3. Consequently, Part 3 of the Guideline also needed to be adapted to the new standards for the execution of concrete structures. The Comment on the 2012 edition of the "Steel Fibre Reinforced Concrete" Guideline are split into two parts. The provisions of the Guideline are explained in Part A which is presented in two columns, the text of the Guideline being reproduced on the left and the explanatory notes being given on the right. Part B of the Comment contains background information on the safety concept, the derivation of the design residual tensile strengths and aids to application of the Guideline in the form of design charts. The Comment was elaborated by the Steel Fibre Reinforced Concrete Subcommittee of the DAfStb and subsequently submitted to the DAfStb's Design and Construction Technical Committee. They were thus approved using a procedure similar to that employed in standardization work, in other words, with a consensus of opinion being reached by all parties involved.
