Abstract: Operational modal analysis allows one to identify the modal properties (natural frequencies, damping ratios, mode shapes, etc.) of a constructed structure based on output vibration measurements only. For its high economy ...

Abstract: In full-scale ambient vibration tests, many situations exist where it is required to obtain a detailed mode shape of a structure with a limited number of sensors. A common feasible strategy is to perform multiple setups ...

Abstract: Many spectacular pedestrian bridges were designed and constructed recently. Owing to their special shapes, it is expected that various types and a wide range of vibration frequency components will be induced by pedestrians. ...
