| 摘 要： | 根据伸臂结构的简化模型和伸臂与外框柱的变形协调条件,考虑伸臂的实际刚度,导出伸臂对核心墙的附加力矩,求得结构顶点侧移。对伸臂位置变化引起的侧移变化与内力突变进行了分析,结合工程分析结果对高层建筑加强层设计提出了一些参考意见。

| Abstract: | This paper presents the restraining moments acting on the core wall due to outriggers and the equation of the top horizontal displacement based on a simplified outrigger model.The deformation compatibility conditions between outriggers and the core wall as well as the finite rigidities of outriggers are also considered.One case study is carried out to analyze the top horizontal displacement and the mutation of the restraining moments caused by the variation of outrigger location.Some conclusions are valuable to the strengthened story design of high-rise buildings. |

| Keywords: | high-rise building frame-core structure outrigger internal force mutation top horizontal displacement |
