摘要
单管塔因其结构轻巧、造型美观,越来越多地被应用于城市及对环境有美观要求的地方。通信单管塔属于高耸结构,其受力特点是风荷载起决定作用,高度越高,风荷载的响应越明显。由于通信基站的密度较集中,对于同一地区的风压及地貌相差不大、对通信工艺要求相同的基站,可以规格化塔身主材。针对2类经常建造落地单管塔的地貌,通过对目前运营商常用天线挂高的单管塔结构进行不同风压下的受力分析,给出各参数的选择建议,为工程设计提供一定参考。
Monotubes are increasingly applied in cities and beautiful-needed environments because of their dainty shapes. Communication monotube tower belong to tall structures, and the controlling load is wind force. The higher monotube tower endure the stronger wind force. Communication monotubes＇ main material specifications can be normalized under little difference in air pressure and landforms due to the bases＇ high-density. Typical height monotube towers built on two sorts of grounds under different wind pressure are analyzed. Suggestions are given for the choice of parameters, which may be a reference for the future design.
