Drobyshynets S. Influence of the repeated little cycle loadings on mechanical descriptions of steel fibrous concrete and work of bending elements on its basis.

Influence of the repeated little cycle loadings on prism durability and module of resiliently-plasticity of steel fibrous concrete have been studied in dissertation and have been offered mathematical models for their determination. The little cycle fatigue of steel fibrous concrete is first investigational. Dependences have been determined between tensions and deformations in steel fibrous concrete at a single and repeated little cycle compression and stretch. New experimental information is got about work of steel fibrous concrete and steel fibrous reinforce-concrete bending elements at the repeated little cycle loadings. The methodic of calculations of the tensely-deformation state and durability of normal cuts of steel fibrous concrete and steel fibrous reinforce-concrete bending elements is first developed on the basis of modern deformation model. The recommendations have been developed in relation to application of this methodic in project practice.
