在建的广州新电视塔总高610m,为目前世界最高的电视塔。针对天线与塔体的连接,选出插入式和桁架转换两个连接方案,并对两种方案下结构振型、风致响应、温度作用影响等进行了对比分析。结果表明:插入式方案的塔体顶部混凝土应力较大,桁架转换方案对建筑功能设计影响较大,考虑到安全问题,采用插入式方案作为广州新电视塔塔体与天线的连接方案,并提出了采用内置钢板钢筋混凝土剪力墙等的处理措施。
The new TV tower under construction in Guangzhou totals 610m, the tallest television tower in the world. According to the connection between the antenna and the tower body, the two connecting schemes of inserting and truss conversion are selected, and the influence of the structure mode, wind response and temperature effect under the two schemes are compared and analyzed. The results show that the stress of the concrete at the top of the tower is large and the truss conversion scheme has a great influence on the functional design of the building. In consideration of safety issues, the plug-in scheme is adopted as the connection scheme between the tower and the antenna of Guangzhou New TV Tower The use of built-in steel reinforced concrete shear wall and other treatment measures.
