| 摘 要： | 本文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。对伸臂位置及刚度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 of outriggers acting on the core wall and the equation of the horizontal top deflection based on a simplified outrigger model.The deformation compatibility conditions between outriggers and core wall as well as the finite rigidities of outriggers are also considered.One case study is carried out to analyze the horizontal top deflection and the mutation of the restraining moments caused by the variation of outrigger location and rigidity.Some conclusions are valuable to the strengthened story design of the high-rise building structures. |
