摘要
本文利用国内外的研究成果,提出在考虑混凝土的弹性压缩、收缩、徐变及温度影响时,如何粗略估计超高层建筑结构各部分的竖向变形差异。
When the building height exceeds 100m, the vertical deformation differences between vertical members will cause additional moment and shear force. Hence, it is desirable to develop a method to evaluate the vertical deformation. In this paper, column shortening in a forty-story reinforced concrete building is addressed. The total deformation of a member is assumed to consist of contribution from elastic deformation, creep deformation, shrinkage deformation and thermal deformation.
