［摘要］对某个有扁长平面、超大核心筒高宽比的超限高层框筒结构的整体稳定性进行分析研究，建筑高度为187.10m，核心筒X向与Y向平面尺寸比为1∶4.2，核心筒高宽比为21.5，分析了核心筒与外框柱之间钢斜撑和剪力墙的分布，以及其他各种因素差异对结构整体稳定性的影响，总结了这些因素的影响规律。除此之外，对项目结构设计采用的扩孔自锁锚杆、跃层柱及型钢混凝土转换构件等关键技术进行介绍。结果表明，在核心筒外X向设置少量剪力墙和加大周边框架梁的刚度，能有效提高结构的抗侧刚度，且施工方便、不影响建筑功能。扩孔自锁锚杆具有单根锚杆抗拔力大，经济效益良好的特点。项目中的跃层柱能满足大震稳定性要求。项目中针对于型钢转换构件采取的措施，保证了结构的安全性，方便了现场的施工。

Abstract: The overall stability of an out-of-code high-rise frame-corewall structure with flat-long plane and super-large corewall height-to-width ratio was analyzed. The building height is 187.10m, the X-Y plane dimension ratio of the corewall is 1∶4.2, and the height-to-width ratio of the corewall is 21.5. The distribution difference of steel diagonal brace and shear wall between core tube and outer frame column, and the influence of other factors on the overall stability of the structure were analyzed. In addition, the key technologies such as reaming self-locking bolt, thermocline column and steel reinforced concrete transfer member used in the project structure design were introduced. The results show that the lateral stiffness of the structure can be effectively increased by setting a small amount of shear wall outside the core tube in X direction and increasing the stiffness of the peripheral frame beam. And the construction is convenient, does not affect the building function. Reaming self-locking bolt has the characteristics of large pulling force and good economic benefit. The cross-layer columns in the project can meet the stability requirements under rare earthquake. The measures taken for the steel reinforced concrete transfer members in the project ensure the safety of the structure and facilitate the construction on site.
