框架-核心筒结构由于具有较强的抗侧向刚度和杰出的空间性能,结构自重轻,其布局形式有利于建筑整体的受力性能,在高层和超高层建筑中得到普遍应用。超高层建筑通常结构功能复杂,使用性强,体型巨大,内部垂直交通等服务设施的空间合理设计至关重要。框架-核心筒结构中筒芯刚度大,能接受较大的地震剪力,使连梁先屈服破坏,而筒体能持续工作,框架结构主要承受竖向荷载,与筒芯保持良好的整体受力性,因此,在遇到地震作用的情况下,筒外框架柱的破坏程度要大于核心筒。本文综述框架-核心筒结构功能和受力特点以及高层建筑发展。
The frame-core tube structure has a low self-weight due to its strong lateral rigidity and outstanding space performance. The layout of the frame-core tube structure is conducive to the stress performance of the whole building and is widely used in high-rise and super-tall buildings. The structure of super high-rise buildings is usually complex and functional structure, large size, internal vertical transport and other service facilities, space and reasonable design is essential. In the frame-core tube structure, the core rigidity is large, which can accept large seismic shearing force, so that the connecting beam first will yield and destroy, while the tube body can continue to work. The frame structure mainly sustains the vertical load and maintains a good overall force with the core Therefore, in the case of earthquake, the failure of the outer frame column is greater than that of the core barrel. This article reviews the framework - core tube structure features and stress characteristics and high-rise building development.
