 note = {The inelastic instability of cantilever columns with tapered square hollow section under the combined action of axial force, biaxial bending and torsion is studied. A new elastic-plastic tangent stiffness matrix for members with closed thin walled section is used to investigate the behavior. The stiffness matrix uses a tangent coefficient matrix obtainedd by the numerical integration of the hardening moduli of the fibers about the member section to calculate the generalized plastic strain increments. The effect of torsion is considered in the fiber level using von Mises yield criterion. The ultimate strength of the columns is obtained by using extended Horne's stability criterion, and the results are presented in the form of interaction diagrams., 長崎大学工学部研究報告 Vol.25(45) p. 143-149, 1995},
