摘要：

In this paper an analytical method is developed to identify the Bouc-Wen model parameters from the experimental data of periodic loading tests. The model parameters are determined by closed analytical relationships such as the predicted and experimental hysteresis loops to have exactly the same maximum force values and coordinates of loop- axes crossing points. Asymmetric hysteretic characteristics are modeled by sewing the solutions of two different Bouc-Wen equations, corresponding to negative and positive values of the imposed cyclic displacement. The method efficiency is illustrated by its application to portraying the asymmetric hysteretic behavior of two vibration control devices.
