在塔设备设计中如何判断是否加框架支撑

How to Judge Whether Frame Support Should BeDesigned for Tower Equipment Plan

高径比 (H/D)较大的塔在风载荷的作用下 ,在塔顶处会引起一定的静挠度。因此在完成初步的塔设计后 ,还要验算塔设备的挠度值是否在允许的范围内 ,进而决定塔是否需要加框架支撑。本文通过实例中对塔的强度及挠度的计算 ,来判断是否加框架支撑。

There appears some flexibility at the top of tower with high ratio of height to diameter (H/D),caused by wind load.So after tower design is finished,whether flexibility is within allowable scope should also be considered,then whether frame should be appended or not can be decided.Whether frame support is needed or not is estimated by example calculation of tower s flexibility and strength in this paper.
