因为现行GB 50009—2012《建筑结构荷载规范》提供的自振周期经验公式的计算结果与实际计算结果有些差异,导致结构安全性可能存在隐患,通过介绍几种基于结构力学基本原理求解钢结构单管通信塔基本自振周期的方法,并与SAP 2000软件计算的结果进行比较分析,得出可用于指导实际设计的结构基本自振周期的估算公式,该结果与SAP 2000分析软件的计算结果吻合较好。
Because the current GB 50009-2012 “Building Structure Load Specifications” provided by the vibration cycle empirical formula calculation results and the actual results are somewhat different, resulting in structural safety may be hidden dangers, by introducing several basic principles of structural mechanics to solve the single steel structure The basic self-vibration period of the tower is compared with that of the software SAP 2000 and the formula for estimating the fundamental vibration period of the structure that can be used to guide the actual design is obtained. The result agrees with the calculation result of SAP 2000 better.
