Vertical deformation difference analysis of super high-rise hybrid structure with core tube offset
In the super high-rise hybrid structure with core tube offset,due to the difference in stress level between the core tube and the outer frame,there will be a large deformation difference under gravity load.The difference in vertical deformation will have an adverse effect on both structural and non-structural components.It may cause damage to non-structural components such as curtain walls,partition walls,electromechanical pipelines and elevators,causing problems in durability and architectural appearance.It may also cause serious additional internal forces in components such as outrigger trusses.At present,there are few studies on the vertical deformation difference of super high-rise hybrid structures with core tube offset at home and abroad.Taking a super high-rise structure as an example,the vertical deformation difference of the super high-rise hybrid structure with completely offset core tube was analyzed and studied in detail,and the countermeasures and suggestions are put forward.
