| 摘 要： | 研究了有双轴对称截面开口薄壁压杆与多个弹性支承偏心连接时的弯扭屈曲,把作用在开口薄壁压杆上的弹性支承去掉,代之以相应的未知外力和未知扭矩,采用Laplace变换推导出了开口薄壁压杆弯扭屈曲的位移函数,求得了其弯扭屈曲的特征方程。

| Abstract: | The flexural-torsional buckling of thin-wall open compression members with twin axes eccentrically connecting with multiple elastic supports is studied.The corresponding unknown force and torsion are used to replace the elastic torsional supports acting on the thin-wall open compression members,and the displacement function is gained with Laplace Transformation,then the flexural-torsional buckling characteristic equation of the thin-wall open compression members is gained. |

| Keywords: | thin-wall compression member elastic support eccentrically connecting flexural-torsional buckling |
