本文提出了一种由正弦激励下的稳态响应确定单自由度滞回结构动力-挠度关系的方法。所需的数据是谐振频率和等效粘性阻尼因子，如本文所定义的，作为稳态响应振幅的函数。该方法适用于Masing型振荡器，这是一种包括更常见的屈服行为模型（例如，弹塑性、双线性滞后）。文中给出了该方法应用于滞回结构数学模型和动力试验数据的实例。
A method is developed for determining the dynamic force-deflection relation of a one-degree of freedom hysteretic structure from the steady-state response to sinusoidal excitation. The data needed are the resonant frequency and the equivalent viscous damping factor, as defined in the paper, as functions of the amplitude of steady-state response. The method is applicable to oscillators of the Masing type, a classification which includes the more common models of yielding behavior (e.g., elasto-plastic, bilinear hysteretic). Examples of the application of the method to mathematical models of hysteretic structures and to dynamic test data are given.
