单管通信铁塔结构基本自振周期分析及抗震应用

ANALYSIS AND ASEISMIC DESIGN OF FUNDAMENTAL NATURAL PERIOD OF COMMUNICATION SINGLE-PIPE TOWER

摘要: 利用ANSYS软件分析了单管通信铁塔结构的基本自振周期特性,针对不同高度和不同圆形外平台数量进行大量参数分析,得出了在不同参数下单管塔的基本自振周期,并通过有限元计算结果拟合出估算单管通信铁塔结构的基本自振周期的实用计算公式,对实际工程的抗震设计工作有一定参考价值。

Abstract: The fundamental natural period of communication single-pipe tower were analyzed systematically with software ANSYS,Though a large amount of different parameters,such as height of tower and the number of platform,the more practical formula to estimate the fundamental natural period is recommended through fitting a lot of finite element models analysis results.It is more suitable for practical engineering design.
