In this paper, a high‐rise frame‐core tube structure with strengthened stories and high‐position connections, a new landmark building in Wuhan, whose height is 238.6 m, is selected as an example. Construction simulation analysis is carried out by the finite element analysis software ETABS to study the vertical deformation and deformation difference of vertical members under the gravity load, taking the influence of construction processes and shrinkage and creep of concrete into consideration. The results show that there is a significant difference between the vertical deformation of the twin‐tower model with connections and that of the single‐tower model. Some engineering countermeasures are put forward to reduce the vertical deformation difference of the twin‐tower connected structure.

具有高位置连接的高层建筑的垂直变形分析

本文以具有高层结构和高位置连接的高层框架芯管结构为例，选择武汉一座新的地标建筑，其高度为238.6 m。利用有限元分析软件ETABS进行了施工模拟分析，研究了重力作用下竖向构件的竖向变形和变形差，并考虑了施工过程以及混凝土的收缩和蠕变的影响。结果表明，带连接的双塔模型与单塔模型的竖向变形之间存在显着差异。为减小双塔连接结构的竖向变形差异，提出了一些工程对策。
