[提要]  借助于實(shí)際工程的現(xiàn)場(chǎng)實(shí)測(cè)結(jié)果，對(duì)高層建筑豎向構(gòu)件變形差的形成機(jī)理及影響因素展開(kāi)了深入的研究，建立了一套豎向構(gòu)件變形差簡(jiǎn)化計(jì)算公式，并且提出了一些針對(duì)豎向變形差的工程對(duì)策。
[關(guān)鍵詞]  豎向變形差  徐變  收縮  軸壓比

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
