Basic Research to Improve the Inelastic Performance of Resizing Algorithms

재분배 기법의 비선형 특성 개선을 위한 기초 연구

Recently, the resizing algorithms based on the displacement participation factors have been developed for sizing members to satisfy stiffness criteria. It is proved that this resizing algorithms made for utilizing worker's stiffness design are practical and rational when applied to aseismatic design in the range of elastic until now. However, by the preceding research we confirmed that the inelastic performance of steel moment-resisting frame designed by resizing algorithms is not better than that of the frame before resizing. We present therefore a plan for improving inelastic performance of steel moment-resizing frame to which resizing algorithms applied in this paper.
