Abstract:

There are many risks of instability in the process of lifting and closing the corridor steelstructure of a super high-rise tower,which may lead to major safety accidents and economic losses.Taking the Tower C project of the Shenzhen Bay Super Headquarters Base as an example, the wholeprocess analysis method is used to systematically study the risk points of the corridor lifting constructionprocess, including the various stages of the corridor detaching from the support frame, normal lifting, andfinal closure. The finite element software ANSYS was used for numerical analysis, focusing on thestability of the complete process of the corridor detaching from the support frame, the safety of the cablegroup failure during the lifting process, and the influence of environmental temperature changes onstructural deformation and closure. The research aims to minimize the possibility of safety risks andensure that the construction plan has sufficient safety reserves when risks occur.
