CYCLIC BEHAVIOR OF STRUCTURAL STEELS. II: THEORY

Steel structures or components are subjected to complex cyclic stresses beyond the elastic limit under major earthquakes. This paper provides an analytical model of the cyclic behavior of structural steels. The modified uniaxial two-surface model developed by Shen (1992) is generalized to a multiaxial two-surface model, which can treat the cyclic behavior of the structural steels even within the yield plateau. Features of cyclic behavior observed in the uniaxial and biaxial cyclic experiments are included in the present model with the extension of the effective plastic strain range concept into the multidimensional stress state. Researchers predict the cyclic behavior of mild steel under nonproportional biaxial (torsion-compression) loading in experiments (in a companion paper) using the proposed model. The proposed model provides a close fit to the experimental results.
