摘要：

Structural hysteretic force can provide a direct description for the initiation and development of structural damage and can be used for the quantitative structural energy consumption evaluation under dynamic loadings. In this study,a mass distribution and iterative structural hysteretic force identification approach is proposed. Acceleration responses at part of the degrees of freedoms(DOFs) of a nonlinear structure with unknown structure mass, stiffness and damping coefficients are employed for the hysteretic force and mass identification. First of all, the extended Kalman filter(EKF) is ...
