軸方向圧縮力と単調複曲率曲げモーメントを受ける角形鋼管柱の実験的研究材端曲げモーメント比を0.5とした場合

摘要

Recommendation for Limite State Design of Steel Structures and Recommendation for the Plastic Design of Steel Structures specify the requirements for columns to guarantee sufficient strength and ductility. However, deformation capacity of the column which is subjected to compressive axial force with double curvature bending moment is not shown clearly. Moreover, second-order effect under these condition is not investigated by testing. In this study, testing where axial force with double curvature bending moment are applied to the columns are conducted. Moment capacity, deformation capacity and the second-order effects that will be caused by PS moment were evaluated from test results.%本論文では軸方向圧縮力と材端曲げモーメント比κが0.5となる場 合の単調複曲率曲げモーメントを受ける角形鋼管柱について実験を 行い，軸力比，細長比が角形鋼管柱の最大曲げモーメント，塑性変 形能力，変形性状に与える影響を考察した.以下に結論をまとめる.
