Давиденко М. Stress-strain state of fibre concrete elements, reinforced with steel, microcrystalline and basaltic fibre.

Dissertation is devoted to experimental and theoretical research of stress-strain state of new fibre concrete structures, made on technology of the vertical vibropressing, reinforced with steel, microcrystal-line and basaltic fibre. The set possibility of making of effective still fibre reinforced concrete pipes of 400 mm and 600 mm with weight of steel fibre which does not exceed the weight of the cored rein-forcement at the existent making of pipes. The method of calculation of durability of normal circular cuts of fibre reinforced concrete elements on the basis of resiliently plastic diagrams of deformation of material is developed. The mean of determination of maximum deformations of fibre reinforced concrete is of-fered with the use of dependences of potential of loading. With the use of computer model of a wall ring a technical document is developed for reinforcement of wall rings of 2500 мм by a steel anchor fibre and one net in place of two and making still fibre reinforced concrete of well conical rings of 1000 mm.
