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

Environmental and operational effects on modal properties of dams: Foz Tua Arch...

Deteção de danos baseada em vibrações: aplicação a uma barragem de betão

Modal decomposition of the dynamic response of wind turbine during one year of ...

The analysis of the dynamic behavior of wind turbines is a complex task. These structures present diverse configurations, dependent on the wind conditions. Consequently, the dynamic behavior is highly dependent on their operating conditions. This paper analyzes the dynamic behavior of a 2.0 MW wind turbine during 1 year of operation. In that sense, post-processing tools aiming to decompose the measured vibratio...

Vibration-based SHM of transportation and energy infrastructures

Vibration-based damage detection of a concrete arch dam

Civil engineering structures are generally supposed to have long operation life spans during which they are submitted to many factors, both environmentally and human-induced, that degrade their condition and performance, gradually leading to the occurrence of damages and malfunctions. Therefore, systems capable of monitoring and assessing structural performance automatically are highly desirable.& nbsp; In this...

Use of strain monitoring data for fatigue assessment of wind turbine tower

Modal identification of concrete dams with different typologies under natural e...

The Laboratory of Vibrations and Structural Monitoring (ViBest) of FEUP is presently responsible by the development of the research project DAM-AGE (Advanced Online Dynamic Structural Health Monitoring of Concrete Dams). One of the first tasks of this project consists on the performance of ambient vibration tests on concrete dams with different typologies and stiffness characteristics and on the application of ...
