摘要：
This paper proposes a method of output-only modal identification of TV structures via combining the SVM and vector time-dependent autoregressive (VTAR) models for the cases of multiple outputs. Firstly, the formulation of the SVM-based modal estimator for the parameters of VTAR models is derived. Secondly, the bounded quadratic programming (QP) solution of SVM is introduced. Thirdly, the transformation from the estimated parameters to the modal parameters are presented. Finally, the proposed method a series numerical examples validate the proposed method.
