Anti-earthquake Philosophy Design and Simplified Calculation Methods for a Huge Building which Constructed with a Roof Steel Tower

屋顶设置钢塔的高层结构,存在显著的“鞭梢效应”。但是此类工程的设计目前国内尚无专门的规范、规程。本文介绍了屋顶设置钢塔的高层结构抗震概念设计和两类简化抗震设计方法,研究表明,该方法能迅速估算出塔楼的地震作用,其计算结果与有限元整体分析结果误差不大。

The huge building, which constructed with a roof steel tower, has a “whip-sway” effect. However, there are no related domestic specifications or standards so far to be used for such huge building design. This paper introduces the anti-earthquake philosophy design for a huge building which constructed with a roof steel tower as well as introduces 2 simplified calculation methods. In practice, by using these methods, it will be quick to estimate what is the earthquake influence in case of the roof steel tower to be added to a huge building. There is acceptable error when we make a comparison between calculation result and analyzed result.
