【 摘 要 】

To solve problems, associated with the research of the resistance of the normal section of reinforced rubber concrete with fiber bending elements resistance to the action of external loads were produced and tested for cross-bending samples-beams of size 60×120×1400 mm. The percentage of longitudinal reinforcement is set as an optimization parameter in the experiment, has the greatest impact on the resistance of normal sections of the bending elements. The response function was the strength of normal sections. For comparison, was calculated of durability of normal sections for concrete B25 according to the applicable norms.
