Abstract

Numerical simulations for seismic loading analysis require data on the material properties of the element under investigation. This study presents a method for estimating the combined hardening parameters for structural steel with various grades based on available cyclic hysteresis data. Voce isotropic hardening and Chaboche kinematic hardening were selected to reflect the cyclic characteristics of various structural steels. A numerical analysis with the obtained combined hardening parameters generates good results data for a wide range of material properties for structural steels with different yield ratios. Based on the obtained parameters, some simple equations that describe the correlation between the combined hardening model and material properties such as the yield ratio are derived.
