我国近年在北京建成了405m高的中央电视塔,该塔由钢筋混凝土塔身、塔楼和混凝土与钢天线塔杆所组成。为了研究电视塔的动力性能,在常遇地震作用下的反应,和在罕遇强烈地震作用下可能出现的破坏形态,按相似准则制作了8m高的电视塔结构模型,在大型振动台上进行了系列的试验研究。通过试验,得到了电视塔结构的动力性能,塔的地震反应以及在强烈地震作用下塔的破坏形态与机理。研究结果为该电视塔的抗震设计提供了依据。
In recent years, China has built a 405-meter-high central television tower in Beijing. The tower consists of a reinforced concrete tower, a tower and concrete and steel antenna towers. In order to study the dynamic performance of the TV tower, the reaction under the common earthquake, and the possible damage patterns under the action of rare earthquakes, a television tower structure model with an 8m height was produced according to similar criteria, and was performed on a large-scale vibration table. A series of experimental studies. Through experiments, the dynamic performance of the structure of the television tower, the seismic response of the tower, and the damage morphology and mechanism of the tower under strong earthquakes were obtained. The research results provide a basis for the seismic design of the TV tower.
