Plastic Interaction Relationships for Square Hollow
Structural Sections: Lower Bound Solution
Magdi Mohareb, M.ASCE,1 and Istemi F. Ozkan2
Abstract: General interaction relationships for hollow structural square sections subjected to general combinations of normal force,
twisting moments, biaxial bending moments, and biaxial shearing forces are developed. The lower bound theorem of plasticity is
employed to obtain the fully plastic resistance of the section as determined by the maximum distortional energy density criterion.
Previously established interaction relationships for hollow structural sections subjected to bending moments, axial force, and twisting
moments are recovered as a special case of the general solution. The developments are expressed as universal, nondimensional relation-
