抄録

The inelastic behaviors of hollow circular section under the constant axial forces are investigated in terrns of the transforrnations of the yield surfaces presented by the pararneters P/Py, Mx/M*px, and My/M*py, in which Py, M*px, and M*py are the yield axial force and the plastic moments under the monotonic uniaxial loadings respectively. The experirnents and the nurnerical analyses for various loading paths are perforrned and the resultant moment-curvature relations are cornpared with each other to show good agreernent. Furtherrnore, the characteristics of the subsequent yield surfaces for three values of constant axial force are discussed.
