集中质量和面积引起的钢塔风振系数变异

Aberrance of the Vibration Coefficient of Steel Tower under Wind Load

现行《高耸结构设计规范》中风振系数的计算没有考虑局部质量、面积变化的影响。本文结合算例对钢塔风振系数的这种局部变异进行了分析 ,得到了一些有益的结论 ,提出了考虑钢塔局部变异影响的计算方法 ,供工程设计。

The aberrance of the vibration coefficient of steel tower under wind load cuased by aberrance of local mass and outline is not considered in recent applied code. Applied with a numerical example, the fact is discussed and some useful advice is given in this paper.
