| 摘 要： | 推导了工字形截面薄壁楔形构件的稳定计算中的单元刚度矩阵，通过分析对比得出在楔形构件的稳定计算中，如果是弯扭失稳，则必须采用楔形单元矩阵。本文推导出的楔形杆件在任意荷载下的弹性稳定单元刚度矩阵，可用其直接形成总刚度矩阵，解算楔形杆的稳定问题。

| Abstract: | Element stiffness matrix which is applied in stability calculation of I - section thin - wall tapered member is deduced. By analysis and contrast, the conclusion is obtained: in the stability calculation of tapered member , if the buckling is the lateral - torsional buckling, it must use the tapered element matrix to solve the stability problem. |

| Keywords: | tapered element stability element stiffness matrix |
