| Description
| - There is still small use of FRC (Fibre Reinforced Concrete) for FRC load structures, despite increase in its production. Interest of structural engineers and investors still increase in application of FRC load structures, which don´t only increase their safety and durability, but also brings economic effect. The main barrier is the absence of design and implementing standards. The paper includes extract from the prepared Czech standards (ČSN): a) Fibre Reinforced Concrete (FRC) – Specification, Performance, Production and Conformity ČSN 73 2450, b) Testing of Fresh Fibre Reinforced Concrete (FRC) – ČSN 73 2451, c) Testing of Hardened Fibre Reinforced Concrete (FRC) – ČSN 73 2452. Principles, which are included in standards, concern the assessment of fresh and hardened fibre reinforced concrete, which results in classification into FRC strength classes. The paper is dedicated to the tensile strengths of FRC, whose values must be stated in the characteristic strength class of FRC, because they characterize its advantages over plain concrete. The basis for determining characteristic tensile strengths of FRC is the dependence of F/δ recorded during the bending test on beams size of 150/150/700 mm (theoretical span of 600 mm), by the so-called four-point loading arrangement of beam. Diagram F/δ can also be called the diagram of resistance, in which are calculated characteristic tensile strengths for the agreed deflections δt. Tensile strengths are presented in ČSN 73 2450 in the strength classes of FRC. The paper contains the calculation procedure of the tensile strength classes in selected cross sections of the diagram of resistance F/δ, including picture of course of stress at the selected sections, that best describes the behaviour of FRC.
