In given article the results theoretical and experimental researches bent are submitted and is compressed — bent of steel fiber reinforced concrete elements at static and short-term dynamic loads. The valid nonlinear diagram of deformation of steel fibre reinforced concrete and its analytical description is received at short-term dynamic load. Complex experimental researches of work of steel fibre reinforced concrete designs are lead at static and short-term dynamic loads, the new scientific data are received. Methods of calculation of durability and crack-stability such elements are developed in view of nonlinear work of concrete, armature and steel fiber reinforced concrete. The grant devoted to an estimation of a technical condition, to restoration and amplification of ferro-concrete designs of buildings and constructions with application of steel fiber reinforced concrete is developed.
