三角形角筒の曲げ崩壊に関する研究

抄録

Collapse load estimation method for square tubes under bending was proposed by Kecman. According to the study, there are two types of collapses. The first type is a collapse due to buckling at the compression flange. The second type is a collapse due to plastic yielding at the flange. Then, the purpose of this study is to investigate whether the Kecman's method can be extended in estimation method for triangle tubes under bending. The validity of the collapse load estimation is checked by the results of FEM numerical analysis.
