摘　　要：以宁波中银大厦为工程背景,采用midas/gen有限元软件,对超高层建筑进行了考虑混凝土收缩徐变的施工模拟分析。计算采用CEB-FIP (1990)规范中的混凝土收缩徐变模型,得出收缩徐变对结构构件竖向位移及位移差的影响。结果表明:收缩徐变使高层建筑结构产生较大的竖向变形和竖向变形差,必须对结构进行考虑收缩徐变的施工过程分析。The construction simulation analysis of super high-rise buildings considering the shrinkage creep of concrete was carried out by using midas/gen finite element software with Bank of China Tower in Ningbo as the engineering background. The model of concrete shrinkage creep in CEB-FIP (1990) specification was used to calculate the effects of shrinkage creep on vertical displacement and dis-placement difference of structural members. The results show that shrinkage creep causes large vertical deformations and differential vertical deformations in high-rise structures, and it is neces-sary to analyze the structure for the construction process considering shrinkage creep.
