| 摘 要： | 用弹性薄壁柱理论,推导了开口任意截面柱弯扭屈曲相关方程,并由此简化到单轴对称截面、双轴对称截面经典方程。进而研究了L形柱轴向受压的承载力即φ-λ曲线,以便工程设计应用。

| Abstract: | The general equations of torsional-flexural interactive buckling for abnormity thin-walled open sections columns by means of the theory of elastic thin-walled column have been derived. Then the general equations have been simplified to the classical buckling equations of the columns with one or two symmetry axis cross sections. The bearing capacity i.e. φ-λ curve has been studied for a thin-walled column of L-section subjected to longitudinal compress so as to be applied in engineering. |
