Evaluation methods based on stress resultant for seismic performance of steel members with fiber model

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