带加强层框—筒结构中水平伸臂最佳刚度研究

Research of the Optimum Stiffness of Outriggers in Frame-tube Structures

利用带水平伸臂的框架—筒体结构侧移公式,对带加强层的框架—筒体结构水平伸臂的最佳刚度进行了分析,明确给出了根据需要减少的结构侧移量,确定水平伸臂最佳刚度的方法,并给出了具体参数。本文的结论,可供工程设计特别是确定结构方案时参考使用。

By using sidesway calculation formula for frame-tube structures with top horizontal outriggers, the optimization stiffness of outriggers in the frame-tube structures with strengthened story are analyzed the method to determine the optimum stiffness of the horizontal outriggers magnitude and precise parameters base on reduced structure sidesway is presented. The conclusion can give a reference to design and especially to confirming structural scheme.
