The article presents the results of numerical research on finite-element models of flat girderless floors. The influence of geometric parameters on the magnitude and ratio of force factors that occur during the operation of a flat reinforced concrete slab was studied. Force factors include the combined action of the punching force and the bending moment. The variable parameters in the study were the flexibility of the column and the size of its cross-section. The purpose of the study was to substantiate the ratio of the bending moment and the longitudinal force in the column for the development of methods for conducting experimental studies on test samples. Based on the results of the study, the influence of the column’s flexibility and the dimensions of its cross-section on the ratio of the studied force factors was established. The study made it possible to choose the best option for loading test samples. The results of the study were used to conduct experimental studies on the punching of flat reinforced concrete slabs.
