The article presents the results of studies of the mechanism of force transfer through cracks in reinforced concrete elements. New results for estimating the ultimate shear resistance and stiffness of sections with cracks are reflected. Tests of prototypes of the were carried out in a hydraulic press. To install the test sample into the press, without changing the value of the initial crack width obtained as a result of splitting, a special rigid frame made of metal corners was made during the sample turning.
