预应力高耸塔筒结构的受力特性不同于普通小型构件。为了确定其正常使用极限状态下截面刚度的计算公式 ,本文通过一个预应力电视塔的例子 ,用几个不同的预应力刚度公式的计算结果进行比较和分析 ,从而得到预应力高耸结构塔筒截面正常使用极限状态下的刚度降低系数。
The prestressed towering tower structure is different from the ordinary small-size components. In order to determine the calculation formula of section stiffness at its normal serviceability limit, this paper compares and analyzes the results of several prestressed stiffness formulas by using the example of a prestressed TV tower to obtain the prestressed high-rise tower section The stiffness reduction factor under normal use.
