Analysis of the theory of calculation of fiber-reinforced concrete with non-steel fibers

Abstract

Abstract The fiber-reinforced concrete finds more applications in modern construction. This material has improved strength and deformation characteristics. The fiber-reinforced concrete is considered to be one of the most promising building materials in the world practice. The experience of using this material in developed countries, such as the USA, UK, Japan, Germany, Italy, France, Australia, has shown the good technical and economic indicators in building constructions. Recently, the base of standards for preparation, calculation and design of such concretes has been prepared and introduced in Russia. The method of determination of the class of the fiber-reinforced concrete by residual tensile strength, the calculation of the strength of standard sections, the diagrams of the deformation is discussed in the article based on the new Code of Practice. The obtained results of analysis of the theory of calculation suggest further studies of the properties and physical characteristics.
