The article deals with the results of the research and analysis of the influence of an initial deflection on movements and deformations of the reinforced flexible plates, loaded by not symmetric transverse force. The flexible plate from the material St3 has been accepted as a design model. The plate has been divided into 2 panels, square in respect of (a × b = 50 × 50 (cm)). The rib with the eccentricity with respect to a middle plane of the plate has been put on the center of the plate. The plates have been considered in thickness of 0,7h, h: and 1,5h (h = 1 cm). The size of ribs bp × hp = 3 × 3; 4 × 4; 4 × 6 (cm), respectively, has a symmetric initial deflection. To analyze the stress-strain state, deflection diagrams and strain intensity graphs have been constructed and analyzed, depending on the magnitude and direction of the initial deflection at different values of the transverse force, causing both elastic and elastic-plastic deformations.
