Buckling Reference Table for Plates

This document provides a reference table for buckling checks of plates under different loading conditions. It lists the type of load, required geometry properties, material properties, loading values, buckling factors, and results. It then shows example values for plate geometry, material properties, loading, buckling factors, and checks that the loading is below the buckling resistance capacity. Buckling checks are required as the plate width is shorter than the length.
