偏心を有する鋼構造強柱立体骨組の等価1質点3自由度系への置換（弾性応答に関する諸量）

摘要

This research is concerned with plastic deformation demand of energy absorption members in strong column type steel moment frames with eccentricity. And it proposes equivalent single mass and tri-degree of freedom systems based on energy conservation law. This paper confines to elastic response and discusses the validity of the systems according to comparison with earthquake response of the systems and that of space frame models using fishbone-shaped frames.
