摘要
从塔架压杆的稳定计算出发,介绍了一种具有弹性支承的压杆模型,并对其临界荷载进行了计算,其结果较以往模型准确、安全性好,可供相关设计选用。
Based on the stability calculation of compressed poles for tower truss,a model for compressed bar with elastic support is introduced and its critical load is calculated as well.The result is more accurate than that of the former model and the safety is better,too.The result can be adopted in related design.
