MODAL ANALYSIS AND VERIFICATION PERFORMED TO CYCLIC SYMMETRIC STRUCTURES BASED ON STOCHASTIC SUBSPACE IDENTIFICATION

Jixie qiangdu, 2016
To determine whether stochastic subspace identification（ SSI） based on the output-only measurements can identify the doublet modes of cyclic symmetric structures accurately,taking a brake disc as an example,modal analysis based on SSI and traditional ...

Long-Term Structural Health Monitoring of Kashima Lighthouse

Buildings
The Kashima Lighthouse, one of the lighthouses that suffered damage in the 2011 Great East Japan Earthquake, required a careful investigation to estimate its long-term behavior and seismic vulnerability.

Decentralized Multivariate Identification Of Interconnected Systems By A Stochastic Subspace Method

, 2015
In this work an identification methodology for decentralized multivariate identification of serial interconnected systems by a stochastic subspace method is proposed. The global system identification is made through the individual identification of these

Subspace discovery for video anomaly detection [PDF]

, 2010
PhDIn automated video surveillance anomaly detection is a challenging task. We address this task as a novelty detection problem where pattern description is limited and labelling information is available only for a small sample of normal instances.

Application of Covariance Driven Stochastic Subspace Identification Method

, 2022
In this research the application of output-only system identification technique known as Stochastic Subspace Identification (SSI) algorithms in civil structures is carried out. With the aim of finding accurate modal parameters of the structure in off-line analysis, a stabilization diagram is constructed by plotting the identified poles of the system ...

Modal Identification Method of Offshore Wind Turbine Tower Based on SSI and FSDPC

Shock and Vibration
The structural health monitoring of offshore wind turbine towers is critical for ensuring their operational integrity. The condition of the tower structure is characterized by its modal parameters, which serve as effective health indicators.

Structural Health Monitoring of Steel Garage Model with Stochastic Subspace Identification–Covariance Variance Analysis

Buildings
Traditional methods of determining structural dynamic parameters produce destructive and unreliable results. Therefore, in this study, operational modal analysis method, which is a non-destructive and advanced method, was used to determine structural ...
