单管塔顶点位移的快速计算方法

摘要

The accurate results of the monopole’ s top displacement can be obtained with finite element software modeling, but the calculation process of the method is complicated. In this case, the paper proposes a rapid calculation method of the monopole’ s top displacement, and the method can get the top displacement of monopole fast by applying EXcellspreadsheet for editing and expanding formula. The numerical example results show that the difference of the rapid calculation method’ s results and the finite element analysis’ s results is small, and it proves that the rapid calculation method can be used to compute the top displacement of monopole.%鉴于采用有限元软件模拟计算单管塔的顶点位移能得到精确的结果，但其计算过程较复杂，提出了一种单管塔顶点位移的快速计算方法，采用EXCEL表格编辑并拉公式，可以快速得到单管塔的顶点位移，算例结果表明，快速计算方法与有限元计算结果相比误差很小，说明使用该方法计算单管塔顶点位移是可行的。
