本研究では，径厚比60， 細長比20近傍のパラメータを含む径厚比55や細長比70程度の円形鋼管部材の繰返し載荷実験を行い，実験データベースを拡充し，座屈耐力や座屈性状の分析，座屈後履歴則や破断時期予測手法の適用性検証を行い，最後に有限要素法を用い た局部歪の補完解析を実施しました。論文はこちら
It is known that circular hollow section members used in truss towers are subjected to cyclic loading after bending buckling, which leads to early member failure. In this paper, cyclic loading tests of circular hollow section members are conducted to verify the applicability of the buckling behavior. In addition, a replication analysis is performed by FEM analysis to verify the applicability of the prediction method for the rupture timing.
