[提要]  借助于实际工程的现场实测结果，对高层建筑竖向构件变形差的形成机理及影响因素展开了深入的研究，建立了一套竖向构件变形差简化计算公式，并且提出了一些针对竖向变形差的工程对策。
[关键词]  竖向变形差  徐变  收缩  轴压比

By means of field measuring results, the causes and effect factors of vertical deformation difference are deeply studied in the concrete high-rise building.A set of simple equation of different vertical deformation is developed for the building structure,and some countermeasures are also suggested.
Keywords:  concrete structure;  high-rise building;  vertical deformation difference; creep strain; shrinkage
