Abstract

This paper aims to propose the methods for evaluating the seismic performance of stiffened steel box members in consideration of hysteresis. The previous study pointed out that the seismic evaluation results on the basis of strain are affected by the hysteresis. In this paper, the curvature or the intersectional force is focused on as proper parameters for evaluating seismic performance of steel members. Then, the seismic evaluation methods by using the curvature or the intersectional force are proposed because the curvature or the intersectional force is hardly influenced by the hysteresis. The validity of proposed methods was confirmed by comparing with experimental data and analysis data in the previous studies. Furthermore, the possibility of applying the proposed method by using intersectional force to the steel members under 2 axis bending moment or torsion is indicated.
