摘要:塔吉克斯坦国家标志塔是一座集旅游观光、展览、餐饮、娱乐、休闲等综合服务功能的观光塔。该塔高度较高,体型瘦小,塔身外附有沿塔身螺旋上升的装饰性螺旋管。系统地介绍了该塔各部位结构方案选型和关键构件的连接方式,并对结构在地震作用下的位移指标进行控制。采用YJK和LIRA-SAPR 2017 R4软件对结构整体进行小震弹性分析,并用YJK软件对结构进行静力弹塑性分析;根据该塔自身结构形式的特殊性,从重要构件的内力分析等角度分析了结构的合理性和安全性,同时提出此类高耸结构设计中的注意事项以及相应的结构设计方法。结果表明:结构安全可靠,结构的振动特性、局部与整体的位移等指标均满足设计要求。

Abstract: The Tajikistan National Symbol Tower is a sightseeing tower that integrates tourism sightseeing, exhibition, catering, entertainment, leisure and other comprehensive services. The tower is high in height and small in size, and a decorative spiral tube spiraling up along the tower is attached to the outside of the tower. The structural scheme selection of each part of the tower and the connection method of key components were systematically introduced, and the displacement index of the structure under the action of earthquake was controlled. YJK and LIRA-SAPR 2017 R4 softwares were used to carry out frequently-occurred earthquake elastic analysis of the whole structure, and YJK software was used to carry out static elastic-plastic analysis of the structure. According to the particularity of the tower structure itself, the rationality and safety of the structure were analyzed from the perspective of the internal force analysis of important components. At the same time, the precautions in the design of this towering structure and the corresponding structure design methods were also proposed. The results show that the structure is safe and rational, and the vibration characteristics of the structure, local and overall displacement and other indicators meet the design requirements.
Keywords: Tajikistan National Symbol Tower; high aspect ratio; spiral tube; spatial structure
