Predicting the Dynamic Behaviour of a Concrete Dam using Statistical and Machin...
Pereira, S; Mata, J; Magalhães, F; Gomes, J; Cunha, A.Operational Modal Analysis is a reliable methodology for the assessment of civil engineering structures, allowing for the accurate definition of their dynamic behaviour. Additionally, since it does not require the use of artificial excitation, it becomes a cost-effective choice for the performance of singular tests, as well as a consistent option for the long-term continuous monitoring of structures. Neverthele...

Cunha, A.; Pinto, J.; Cerqueira, M. F.; Silva, F. S.; Trindade, B.; Carvalho, O.Multi-material structures make it possible to obtain effective solutions to engineering problems by combining the benefits of different materials to meet the requirements of different working conditions. The aim of this multifunctional 420 stainless steel-copper structure is to create a hybrid solution in which copper acts as heat-transfer enhancer (through cooling channels) while maintaining the required mecha...

Cunha, A.; Pereira, S.; Pacheco, J.; Pimenta, F.; Moutinho, C.; Magalhães, F.The continuous application of Operational Modal Analysis (OMA) to time-series recorded on civil engineering structures, and the subsequent tracking of modal properties, allow the characterization of the evolution of their dynamic behaviour, which is particularly important on wind turbines, since their structural performance is highly dependent on it. However, it is impractical to manually analyse long periods o...
Dynamic Monitoring of a Cable-Stayed Bridge: Monitoring System and First Results
Sérgio Pereira; Magalhaes, F; Caetano, E; Cunha, A.; Toullier, T; Dumoulin, JThe Eric Tabarly bridge in Nantes is a 210 m long cable-stayed road bridge crossing the Loire River, that was inaugurated in 2011. It is composed of a 27 m wide steel deck divided into two spans by a 57 m high steel pylon, being the main span 143 m long. In the context of the European Research Project DESDE-MONA (DEtection of Steel DEfects by Enhanced MONitoring and Automated procedure for self-inspection and m...
