Abstract
The paper analyzes the effect of the compressed zone of concrete on the shear resistance of reinforced concrete flexible beams. The calculation models are considered, by which the contribution of the compressed zone of concrete to the total value of the shear resistance is further determined. The features of each model are described, and schemes and dependencies for calculating the transverse force in the compressed zone of concrete are presented. The experimental database of specimens is presented and the analysis by the considered calculation models is carried out. Varying parameters in the database are marked and the analysis by the obtained calculated values of transverse force in the compressed concrete strip by models is performed. The contribution of the transverse force in the compressed zone to the quantitative contribution to the shear resistance is indicated and appropriate conclusions are drawn on the models presented and the parameters considered.
