本文针对目前国内外对偏心结构地震荷载的计算方法中存在的问题,利用反应谱理论,按振型组合方法估算了单层单向偏心结构中单片框架的最大位移反应值,推导并计算了单片框架上的剪力放大系数α和结构的动力偏心距放大系数β。通过计算对比,建议放弃动力偏心距的概念,直接用剪力放大系数(即α系数)计算。列出的α数值图表可供实际设计参考。
In this paper, according to the problems existing in the calculation method of seismic loads for eccentric structures at home and abroad, the maximum displacement response value of a single frame in a single-layer one-way eccentric structure is estimated by the response spectrum theory and derived and calculated. The shear amplification factor α on the monolithic frame and the dynamic eccentricity amplification factor β of the structure. By calculating and comparing, it is recommended to abandon the concept of dynamic eccentricity and directly use the shear amplification factor (ie, α coefficient) to calculate. The alpha values listed are available for practical design reference.
