旋转斜柱框架-核心筒超高层结构受力分析与设计

对于旋转斜柱框架-核心筒结构,斜柱的存在会使斜柱本身、核心筒、梁和楼板产生比普通直柱结构更复杂的受力情况,使得旋转斜柱产生的水平扭矩对楼板传递扭矩的能力及核心筒的抗扭能力提出新的要求,需要考虑结构在竖向荷载下的变形和内力作为水平荷载分析工况的初始条件等。结合工程实例提出了该特殊体型结构设计的关键技术,研究了旋转斜柱对结构整体性能以及对楼板、核心筒等构件的影响,以及针对传力体系的特殊性和设计难点所采取的加强措施,确保该类结构的安全性。

Analysis and design of supper high-rise frame-corewall structure with rotating inclined column

For the frame-corewall structure with rotating inclined column, the existence of the inclined column will make force condition of the inclined column itself, the core tube, the beam and the story-slab more complex than the traditional frame-corewall structure. The horizontal torsion caused by inclined columns makes new requests on the ability of story-slab transferring torsion and the torsion resistance of the corewall. The deformation and internal force of the structure under vertical load should be considered as an initial condition of analyzing the structure under horizontal load. Combined with engineering example, key technologies of this special structure system were put forward, and research of the influence of rotating inclined columns on the overall structural performance and the effects on mainly structure including the story-slab and corewall were carried out. Strengthen strategies were adopted for the particularities of the force transmission system and designing difficulties to ensure the safety of the structure.
