Abstract

The fiber model which is one kind of frame analysis methods is sometimes used as an effective tool for the nonlinear dynamic response analysis. Recently, some seismic evaluation methods based on the strain for evaluating the seismic performance of stiffened steel box members were proposed. However, it is reported that these previous methods based on the strain cannot adequately estimate the seismic performance. In this study, it is explained that the stress resultant can be little affected by hysteresis patterns and have the ability to be a good parameter in order to evaluate the seismic performance appropriately. In addition, a seismic evaluation method based on the stress resultant with the fiber model is proposed for evaluating the seismic performance of stiffened steel box members. Finally, the validity of the proposed method is confirmed for stiffened steel box members by comparing the calculation results by the proposed method with the experimental results and FEM analysis results.
