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.
