SummaryIn this paper, the governing equations of the outrigger‐braced structure are formulated by considering the influence of core‐wall width. The axial forces in the columns are considered as unknowns and the compatibility of the column's axial deformation is considered in formulating the governing equations. Then, the governing equations for the optimum locations of outriggers are formulated by minimizing the top drift of central core wall. After that, the influence of core‐wall width on the optimum outrigger locations, the drift‐reduction efficiency and moment‐reduction efficiency is investigated numerically. Some results are presented for the reference in the preliminary design of the outrigger‐braced structures.

核心筒宽度对支腿支撑结构优化分析的影响

摘要本文考虑核心墙宽度的影响，建立了支腿支撑结构的控制方程。在制定控制方程时，将柱中的轴向力视为未知数，并考虑柱轴向变形的相容性。然后，通过最小化中心核心筒顶部漂移，制定支腿最佳位置的控制方程。之后，数值研究了核心壁宽度对最佳支腿位置、减少漂移效率和减少力矩效率的影响。给出了一些结果，供支腿支撑结构初步设计时参考。
