三管塔结构基本自振周期分析及应用

摘要

利用空间钢结构系统CAD软件3D3S分析了三管通信铁塔结构的基本自振周期特性,建立不同高度和不同圆形外平台数量的模型进行大量参数分析,计算了在不同参数下三管塔的基本自振周期,并通过3D3S模型计算结果拟合出估算三管通信铁塔结构的基本自振周期的实用计算公式,对实际工程的设计工作有一定参考价值。%The paper analyzes the fundamental natural period of three-tube corresponding iron tower by adopting CAD software 3D3S of the space steel structure,establishes the models with various heights and circular external platform number to have a lot of parameters analysis,calculates the fundamental natural period of three-tube corresponding iron towers with different parameters,fits the practical calculation formula for the fundamental natural period of three-tube tower according to the calculation results from 3D3S model,so as to have the reference value for the design in the factual projects.
