Analysis On Differential Vertical Deformation Of High-rise Frame-tube Structure System

With the development of the economy, high-rise building structure system is usedwidely. In recent years, the layout of high-rise building structure system is becomingmore and more complex; the problem of high-rise hybrid structure system in theconstruction process is also becoming more and more complex. Among them, a keyquestion is that the vertical deformation difference brings hidden trouble to theconstruction and the structure. This hidden danger not only affects the constructionquality but also affects the safety of the whole structure. This paper takes the frame ofcore tube structure in Handan as an example, starts from the vertical deformation impactfactors and the calculation method of the vertical deformation difference of verticalcomponent, analyses and discusses the measures to weaken the vertical deformationdifference.For the first question, we checked to relevant literatures, summarized the influencefactors which influence the vertical deformation difference. In the end, we puttedforward measures to weaken vertical deformation from the aspects of materials, design,construction measures.For the second question, firstly, the paper analyzed the changing rule of verticaldeformation difference under different loading modes. Secondly, the paper discussed theadditional internal force question caused by vertical deformation difference and thequestion of shear stirrup configured being high and so on, at last the paper put forwardthe improvement measures.Through the above work, the paper obtained the calculation rules of the verticaldeformation difference under different loading modes and studied on the question of theadditional internal force. Finally, the paper analyzed and discussed the measures toweaken vertical deformation difference.
