Structural column: a rectangular cross-section column is formed by two or more steel angles or steel channels connected by junction plates.
格构柱:两个或两个以上的角钢或槽钢用连接板相连而组成的矩形截面的组合柱。
However, the thin-walled steel tubes are prone to local buckling under axial pressure, especially for the square and rectangular cross-section shape.
但是薄壁钢管在轴向荷载下容易发生局部屈曲,尤其是截面形状为方形或矩形时。
In the numerical analysis of axially symmetry electromagnetic field, the finite element method using ring unit with rectangular cross-section has more advantages than other methods.
在具有轴对称特性电磁场的数值分析中,用矩形截面环单元分析具有比其他单元更多的优点。
