摘要
以设置四道外伸臂超高层结构为例，探讨了带外伸臂超高层建筑结构的水平位移计算问题。导出了求解外伸臂约束弯矩的矩阵方程，在此基础上推导了求解顶点水平位移的计算公式，同时探讨了外伸臂抗弯刚度的计算问题。最后给出了算例，说明外伸臂的有效性和计算方法对工程设计的实用性。
Directed against the actual engineering design, a four-outrigger highrise structure will be used to demonstrate the calculation of the lateral deflection. The matrix equation is derived to solve the outrigger restraining moments. On the equation, the formula of the top lateral deflection is derived. At the same time, the calculation of the bending rigid of the outriggers is studied. Eventually a numerical example is given to demonstrate its effectivity of outriggers in reducing the top lateral deflection and practicability of the calculation in the design.
