In the authors' previous paper (part 1), critical response analysis method was modified to be able to consider the influence of the loading history, and its unified formulation for the steel frame structure was presented. Also, in order to verify the validity of the new method, elasto-plastic and finite deformation analyses of the steel brace member subjected to repeated prescribed axial displacement were carried out. In this paper, parametric studies of the steel brace member are carried out with changing the slenderness ratio and the amount of the prescribed axial displacement. Both the ordinary and the modified critical response analysis methods are employed in the parametric studies, which enables us to see the influence of the loading history. It is discussed how those three factors (slenderness ratio, amount of the prescribed axial displacement and the loading history) influence on the behavior of the steel brace member, with attending to the skeleton curve and the steady-state hysteresis curve.
