WebBuckled panels are still effective in carrying shear by diagonal tension. [1] In structural engineering, buckling is the sudden change in shape ( deformation) of a structural component under load, such as the bowing … Webcompression. The limiting resistance (buckling load) is reached, for a steel member, when the combined axial and flexural stresses reach yield stress at some point in the cross section (for a Class 3 cross section) or the bending moment reaches the plastic bending resistance as modified by the axial force (for a Class 1 or 2 cross section). For
