楼顶钢塔一种独特的锚固方式及受力分析

Anchorage of Steel Towers atop Buildings and Structural Analysis

以上海市公安局卢湾分局楼顶加设钢塔为研究对象,介绍了楼顶钢塔的设计方法。通过分析高层建筑上的钢塔在风荷载和地震作用下与下部结构的共同作用,说明在设计钢塔时必须考虑高层建筑对钢塔的影响,并提出一种新型的便于工程应用的钢塔与混凝土高层建筑的锚固方式,可供高层楼顶钢塔设计时参考。

Based on the study of a steel tower additionally added on the top of the building of Luwan branch of Shanghai Police Station, this paper introduces the research of steel towers atop buildings. Through the analysis for the interaction of tower and concrete structure under wind and earthquake, it is shown that the influence of building on the tower must be considered in design. A new Anchoring method between the steel tower and the concrete high-rise building ,which is easy for steel tower design is also presented.
