Dynamic Testing and Continuous Dynamic Monitoring of Transportation, Stadia and...

The Laboratory of Vibrations and Structural Monitoring (ViBest, www.fe.up.pt/vibest ) of CONSTRUCT/FEUP has been implementing, since 2007, a significant set of long-term dynamic monitoring systems in large Civil structures with different typologies (e.g. roadway, railway and pedestrian bridges, stadia suspension roofs, wind turbines, concrete dams or high voltage transmission lines). This paper briefly describe...

First results from the development of a sensing system for bridge construction

Vibration-based SHM of transportation and energy infrastructures

Contribution to new solutions of instrumentation of civil structures for contin...

This paper describes the work developed by CONSTRUCT ViBest research group in the area of new solutions of instrumentation of Civil Structures aiming its long term dynamic monitoring. It identifies the main challenges in this area, and focus the discussion around power options and data transmission solutions. The architecture of the developed measurement systems is described, and a few practical examples of mon...

Monitoring campaign in an onshore wind farm: Installation description and preli...

In the context of the WindFarmSHM project a quite extensive experimental campaign is being performed in Tocha wind farm, an onshore wind farm located in Portugal. This includes the instrumentation of at least two wind turbines aiming the development, validation and optimization of monitoring strategies at the level of the wind farm for damage detection and fatigue analysis, using the response to operation loads...

Modal identification of a double-curvature concrete arch dam under natural exci...

At present time, the accurate estimation of modal properties of large civil structures (e.g. buildings, bridges, chimneys, wind turbines) can be easily achieved by applying state of art output-only modal identification methods (e.g. SSI-cov, SSI-Data, p-LSCF) to the data obtained with ambient vibration tests performed with appropriate sensors and data acquisition systems. However, when dealing with massive stru...

Continuous dynamic monitoring of large Civil infrastructures

This paper briefly describes a set of long-term dynamic monitoring programs developed by the Laboratory of Vibrations and Structural Monitoring (ViBest, www.fe.up.pt/vibest) of CONSTRUCT/FEUP in large Civil structures with different typologies (e.g. roadway, railway and pedestrian bridges, stadia suspension roofs, wind turbines, concrete dams or high voltage transmission lines), showing the interest and potenti...

Proposal of optimum tuning of semiactive TMDs used to reduce harmonic vibration...

Tuned mass dampers (TMDs) are a well-established technology for passive structural vibration control involving harmonic vibrations. Some design issues are critical to guarantee the proper functioning of the device, in particular, the adequate tuning and the adequate space to accommodate the TMD stroke. With regard to the first aspect, semiactive TMDs were proposed as an alternative means of correcting the vibra...
