A plate itself is an essential structural element with wide applications in construction. Also, for thin-walled sections, e.g., I-beams, the load-bearing capacity of their individual walls is determined based on the plate model stability loss. This paper addresses the problem of buckling of a plate reinforced with a rib, which significantly increases its resistance to stability loss. The finite element method was used for the stability analysis, as it allows for stability calculations as a function of all relevant physical and geometric parameters and constraints.Plate structures are commonly used load-bearing elements in construction. Generally, the applied service load is perpendicular to the plate surface, and it operates in a bending state. When the plate load is applied in the mid-plane, a shell stress state occurs for a real plate, which may cause its stability loss. Increasing the plate’s resistance to buckling can be achieved by using a rib.
