摘要：
An eccentric core tube structure is different from the traditional centered core tube structure, where the former exhibits larger horizontal deformation under vertical load, obvious structural torsion, and large tensile stress on the wall piers. Taking a core tube offset structure project as an example, the mechanical performance and economic benefits of the steel structure system and the hybrid structure system are compared. Using numerical analysis methods, the mechanical properties of the structures under different offset degrees and different aspect ratios are studied from both system and component levels. The horizontal deformation and structural torsion indicators of the structure under vertical loads with changing factors such as the degree of placement and the height of the structure are summarized from the system level. The influence of different offset degrees on the mechanical performance of the shear wall is examined from the component level. The results show that, the horizontal deformation of the structure under vertical load can be controlled by pre-elongated frame columns, structural torsion can be controlled by adjusting the shear wall thickness or setting braces, and the wall tensile stress can be controlled by setting section steel or prestressing. © 2023 Science Press.
