摘要
某气象雷达塔拟建于广州市番禺区某山顶。为满足雷达系统需要、成本、技术要求、使用功能及垂直交通的要求,选取混凝土内筒+钢结构外筒结构方案进行计算分析;通过计算分析得出,混凝土内筒+钢结构外筒结构满足各风速工况下的抗风要求;满足结构特殊重量及冰雪荷载下承载力要求;外框筒满足整体稳定性要求;结构的谐振频率、平台塔的摇摆速度及角度满足设计指标要求;内筒满足承载力要求。通过对该项目的结构计算分析,以期对类似建筑的结构设计提供借鉴。
A meteorological radar tower is planned to be built on the top of a hill in Panyu District,Guangzhou Ciy.In order to meet the needs,cost,technical requirements,use functions and vertical traffic requirements of the radar system,the concrete inner cylinder+steel structure outer cylinder structure scheme is selected for calculation and analysis;Through calculation and analysis,it is concluded that the concrete inner cylinder+steel structure outer cylinder structure meets the wind resistance requirements under various wind speed working conditions;Meet the special weight of the structure and the bearing capacity requirements under ice and snow load;The outer frame tube meets the overall stability requirements;The resonance frequency of the structure,the swing speed and angle of the platform tower meet the requirements of the design indicators;The inner cylinder meets the load-bearing capacity requirements.Through the structural calculation and analysis of the project,in order to provide reference for the structural design of similar buildings.
