［摘要］超高層結(jié)構(gòu)豎向壓縮變形不可忽視，其主體結(jié)構(gòu)層間豎向壓縮變形差可能對(duì)單元式幕墻節(jié)點(diǎn)的豎向變形間隙預(yù)留設(shè)計(jì)產(chǎn)生影響。以超高層工程項(xiàng)目為背景進(jìn)行施工模擬計(jì)算，分析不同樓層區(qū)段幕墻構(gòu)件安裝完成后的層間豎向壓縮變形差值，計(jì)算時(shí)考慮豎向荷載、混凝土收縮和徐變等因素的影響；考察各種因素的影響比例；比較不同高度超高層建筑的層間豎向壓縮變形值對(duì)幕墻設(shè)計(jì)的影響。結(jié)果表明，超高層建筑豎向壓縮變形值的增大一般不會(huì)造成超高層建筑幕墻的豎向變形預(yù)留間隙不足的問題。

Abstract:The vertical compression deformation of super high-rise buildings should not be ignored. The vertical compression deformation difference between stories of the main structures may affect the design of the gap reserved for vertical deformation of the frame supported curtain wall assembled in prefabricated units. Based on the construction simulation of the super high-rise buildings, the vertical compression deformation difference between stories in different zones after curtain wall installation was analyzed, and vertical loads, shrinkage and creep were taken into account in the calculation. The influence ratios of different factors were researched. And the influence of vertical compression deformation difference between stories on the curtain wall of super high-rise buildings with different heights was compared. Results show that the increase of the vertical compression deformation value of the super high-rise buildings generally does not cause the problem of the insufficient gap reserved for vertical deformation of the curtain wall of the super high-rise buildings.

Keywords:vertical compression deformation; frame supported curtain wall assembled in prefabricated unit; construction simulation; shrinkage and creep
