［摘要］隨著高層建筑的大量興建和設計建造技術的不斷發(fā)展，核心筒偏離結構平面中心的高層建筑結構也越來越多。采用數(shù)值分析的方法研究了豎向荷載下和大震作用下，核心筒偏置對結構整體受力性能、破壞模式以及構件內力的影響，總結了核心筒偏置結構的受力特點：在豎向荷載作用下，結構樓層受到附加傾覆力矩的作用，結構將產(chǎn)生一定的整體彎曲變形，核心筒偏置相關位置的柱與墻肢軸力也會有所增加。針對這些特點，從結構與構件兩個層面給出了相應的設計對策。

Abstract:With the massive construction of high-rise buildings and the continuous development of design and construction technology, there are more and more high-rise building structures with core tubes deviating from the center of the structural plane. The method of numerical analysis was used to study the influence of the core tube offset on the overall mechanical performance, failure mode and component internal force of the structure under the vertical load and the action of large earthquakes. The force characteristics of the core tube offset structure were summarized: Under the action of vertical load, the structure floor will be subjected to the additional overturning moment, the structure will produce a certain overall bending deformation, and the axial force of the columns and wall limbs at the relevant position of the core tube offset will also increase. In view of these characteristics, corresponding design countermeasures were given from two levels of structure and component.
Keywords:eccentric frame-core tube; high-rise building; mechanical characteristic; failure mode
