摘要：

Single-equation yield surfaces are presented for channel, tee, single- and double-angle sections under combined axial force and biaxial moments. The equations give very good approximations to the accurate yield surfaces while maintaining smoothness, convexity and continuity requirements in three-dimensional space. The equations derived may be implemented in an elasto-plastic analysis program for modelling the nonlinear global behaviour of steel frame structures comprising one or more of these types of section.
