Influence of steel ratio on the vertical deformation of super high-rise building

Taking a super high-rise project as the research object, considering the shrinkage and creep characteristics of concrete and different steel ratio, MIDAS/Gen is used to simulate the construction process of the structure. The results show that different steel ratio has an impact on the vertical deformation and the vertical deformation difference. In the design stage, the reinforcement amount should be increased appropriately, so as to reduce the vertical deformation difference between the core tube and the outer frame column.
