摘要
分析了混合结构超高层建筑竖向变形差的影响因素,阐述了各影响因素包括徐变、收缩、温差效应和弹性压缩的作用机理并给出了其变形计算公式,从设计和施工两方面提出了减小竖向变形差的工程对策,可供工程设计和施工参考.
This paper analyzes the influential factors of the vertical differential shortening in super high-rise hybrid structures,describes the mechanism of influential factors including creep,shrinkage,temperature difference and elastic compression and presents the formulas for calculating the vertical differential shortening.At the same time,the engineering measures for reducing the vertical differential shortening are proposed from both the design and construction in this paper,which provides reference for engineering design and construction.
