| 摘 要： | 通过高层结构弹性和非弹性地震时程反应分析,研究了两者的位移反应关系。结果表明：结构在不同地震作用下非弹性总位移角反应的平均值与弹性反应十分接近,基本符合等位移原则,可以用后者分析结果直接估计前者;结构最大层间位移角反应的平均值在弱和中等非线性阶段亦与弹性反应十分接近,在强非线性阶段则大于弹性反应,经数据拟合,初步提供了一个在此阶段由弹性最大层间位移角反应估计非弹性反应的近似公式。

| Abstract: | In this paper the relationship between the elastic and inelastic seismic displacement responses of high-rise buildings is studied by time history response analysis. The results show that the average roof drifts of inelastic response under different earthquake excitations are nearly equal to those of elastic responses and basically follow the equal seismic displacement principle. The situation is the same for average inter-story drifts of inelastic response in small and middle nonlinear stages but in large nonlinear stage they are larger than those of elastic responses and modified formula is provided for evaluation of inelastic inter-story drifts based on elastic inter-story drifts. |
