Annotation:
The paper offers a technique of nonlinear-iterative calculation for the bearing ability of steel fiber reinforced concrete bent elements using experimental charts of steel fiber reinforced concrete deformation received in the authors` research and in some other sources. Working formulas for determination of deformation modules and the corresponding stresses depending on the experimental charts of material deformation are proposed. The arguments for the well-known calculation formulas and an original flowchart of calculation, as well as practical iterative calculation and the analysis of its results are provided.
