    Abstract. Actual redistribution of moments is required to assess the stress-strain state of continuous reinforced concrete beams. However, in different design standards, the redistribution of moments depends only on the relative height of the compressed zone. The current state of the regulatory framework of various countries in the field of designing multi-span continuous reinforced concrete beams is analyzed, the problems and prospects of using experimental data are identified, and the parameters affecting the redistribution of moments are presented. The results of experimental and numerical studies of the plastic behavior of statically indeterminate reinforced concrete beams are presented. Over 100 experimental samples of two-span reinforced concrete beams were analyzed to determine the main parameters affecting the coefficient of moment redistribution. It is shown that the distribution of bending stiffness across sections plays a crucial role in the behavior of statically indeterminate reinforced concrete beams. To develop a new computational model, new parameters affecting the redistribution of moments have been identified.
    Keywords: statically indeterminate reinforced concrete beams, redistribution of moments, flexural stiffness, plastic hinge, standards of design
