摘要
Abstract
The construction period of a super high-rise steel frame-core tube structure is long,and the stiffness,load and material properties of the structure constantly change during the construction process.There will be vertical deformation differences between the outer frame and the core tube,which will change the stress state of the structure and components and may have adverse effects on the structure.Taking a super high-rise building with the steel frame-core tube structure under construction as the research object,a construction process simulation was conducted.Firstly,the basic laws of vertical deformation of the structure were introduced,and the consistency of the construction simulation results was verified.Then,based on the simulation results,a method for determining the construction leveling value was provided,and the vertical deformation differences and development laws between the outer frame and the core tube of the structure at different stages were analyzed.Finally,based on the analysis results,control measures and suggestions such as vertical deformation difference compensation,advanced construction of the core tube,and delayed rigid connection of the frame beam were proposed to reduce the vertical deformation differences between the frame and core tube,which can provide guidance for similar engineering construction.关键词
