Structural Modal Flexibility Identification Through a Novel Mode Selection Method
Flexibility is an important index in the assessment of bridge load-carrying capacity. Impact testing is an efficient and effective method to obtain the flexibility of small- and medium-span bridges. Modal parameter identification based on excitation and response data plays a key role in flexibility identification, which can obtain the modal scaling factor. As is well known, the combined deterministic-stochastic subspace identification (DSI) algorithm is one of the most popular identification methods. However, unavoidable factors often result in the appearance of spurious modes, which can affect flexibility identification. In this paper, a novel mode selection method is implemented to achieve better extraction of physical modes during the flexibility identification process. A simulated example is used to verify that the proposed method can effectively extract physical modes to obtain a flexibility matrix.
