| 摘 要： | Kelly和周锡元等曾对规则型隔震结构上部单自由度模型进行过讨论，给出了必要的计算公式。对各种中低层规则型隔震建筑，应用此公式可获得满意的结果。近来隔震技术逐渐被应用到高层建筑中。对于高层隔震体系，上部结构的高阶振型效应不能忽略，此时应用单自由度模型将产生较大误差。为此，本文采用上部结构周期和总基底剪力相等的准则，推导了等效模型的结构参数公式，并通过数值模拟分析给出了等效模型简化确定方法。通过对原结构和等效模型结构的地震反应分析，证明了这种等效方法是简便有效的。 |

| Abstract: | Kelly and Zhou Xiyuan etc gave the necessary computing formulas based on the research on upper singledegree-of-freedom model of regular isolated building. For various middle or low isolated buildings, the satisfactory results may be got by using the model. Recently isolation technique was applied to high-rise buildings. For isolated building systems, the high-order mode parts of upper structure can not be ignored. It brings large errors to the results of single-degree-of-freedom model. In the paper, according to the equivalent rules of equal structure period and total base shear, the computing formula of structure parameters is deduced. After numerical analysis for some regular buildings, a simplified method for equivalent model is given. By analyzing the earthquake responses of equivalent model and original structure, it is proved that the equivalent method is simple and feasible. |
