中央电视发射塔(简称中央塔)为钢筋混凝土结构。自室内地坪±0.00计算塔高为386.50m。塔体结构由四部分组成(图1):塔座、塔身、塔楼、天线桅杆。 中央塔为特别重要建筑物,结构设计基准期取100年。经地震危险性评定场地在未来一百年内遭遇9°的超越概率为2％,地震作用相当于9°地震力。中央塔有以下四种预应力混凝土结构:1.竖向:塔身、钢筋混凝土桅杆均为部分预应力混凝土结构;2.环向:基础环板、
The Central Television Tower (CTP) is a reinforced concrete structure. The calculated tower height is 386.50m from the room floor ±0.00. The tower structure consists of four parts (Figure 1): tower, tower, tower, antenna mast. The Central Tower is a particularly important building, and the structural design reference period takes 100 years. After the earthquake risk assessment, the probability of surpassing 9° in the next 100 years is 2%, and the earthquake effect is equivalent to 9° seismic force. The central tower has the following four types of prestressed concrete structures: 1. Vertical: The tower body and reinforced concrete mast are partially prestressed concrete structures; 2. Circular orientation: Foundation ring plates,
