某工程单层椭圆锥面网壳中竖向杆件计算长度的探讨

杆件计算长度是结构设计中的一个重要概念，与该杆件的稳定性控制有密切关系。一般情况下杆件计算长度可参考规范得出本介绍了一种规范未作规定的特殊条件下杆件计算长度问题，并采用铁摩辛柯－里兹法进行了分析。该方法精度较好，适用性强，可供手算，对风类问题具有很好的借鉴意义。

DISCUSSION ON THE CALCULATED LENGTH OF THE VERTICAL MEMBER IN A SINGLE-LAYER ELLIPTIC CONE SHELL

The calculated length of a structural member is a very important conception in structural design, because it was used to control the instability of the member. So the current design codes give the value in most cases. In this paper, an exception about the calculated length of the vertical member in a single layer elliptic cone shell is presented, and the Timoshenko Ritz method is used to analysis this problem. The results show that this method is simple and effective to this kind of problem, and the problem must be paid more attention to in structural design as well.
