| 摘 要： | 在建立和求解Ｔｉｍｏｓｈｅｎｋｏ—Ｅｕｌｅｒ楔形单元平衡微分方程的基础上，利用求得的有限元方程计算了不同边界条件下棋形轴心压杆的弹性临界荷载和计算长度系数。分别研究了楔率和剪切变形对压杆计算长度的影响，并由此得到了相应的实用公式和曲线。

| Abstract: | This paper is to study the effective length of tapered struts with various boundary conditions based on the developed equations for tapered Timoshenko-Euler elements. Effects of taper ratio and shear deformation are investigated respectively on the effective length. Some practical formula and curves are presented by such computation. |
