| Abstract: | The east tower of Zhenjiang Suning Plaza project is a concrete core tube-steel frame structure. The 4 comer columns of the outer frame are in ＂田＂ shape,which is changed into ＂日＂ shape on the top, in the meantime these columns are tilted gradually with an increase in the height of the structure, whose maximum sectional size is 2 500 mm× 2 000 mm; the maximum thickness of the plate is 100 mm and the maximum mass is 9. 5 t/m;the maximum weight of the tilted section of the steel column is 59. 6 t. The binding, lifting and accurate positioning of the tilted steel columns are the key to the smooth construction of this project. Hence the smooth lifting of the tilted steel columns could provide experience for subsequent similar projects. |
