- On dynamic control of structural vibrations research activities conducted within the covicocepad projectPublication . Barros, Rui; Baratta, Alessandro; Corbi, Ottavia; Corbi, Ileana; Braz-César, Manuel; Bairrão, Rogério; Guerreiro, Luís; Magonette, GeorgesThis paper provides an overview on the latest research and development (R&D) activities carried out under the project entitled Comparison of Vibration Control in Civil Engineering Using Passive and Active Dampers (COVICOCEPAD) which was executed within the framework of the Eurocores project, as a part of the sixth European program. The general interest of the paper relies upon the variety of presented highlights relevant to structural control research streams currently under development in a number of European universities, addressing the use of tuned liquid dampers (TLD), base isolation devices, magneto-rheological (MR) dampers and a hybrid technique using both devices together. The paper also provides details of a few new testing equipments which are in use of the relevant laboratories. Finally, research projects in the field of structural control at the involved research institutes are reviewed.
- R&D on control of vibrations under covicocepad during 2007-2008Publication . Barros, Rui; Baratta, Alessandro; Corbi, Ottavia; Braz-César, Manuel; Corbi, Ileana; Bairrão, Rogério; Guerreiro, Luís; Oliveira, C.; Magonette, GeorgesThis paper provides information on the latest R&D within COVICOCEPAD project approved in the framework of Eurocores program. It addresses the use of TLD, base isolation devices, MR dampers and a hybrid technique using both devices together. Some results are provided associated with calibration of a MR damper at FEUP, as well as its inclusion in a small scale laboratory set-up with proper equations of motion of the controlled smart structure. An application of semi-active control technique to a bridge is outlined. Further remarks and details on future tests to be performed in LNEC shaking table, within COVICOCEPAD project, are provided.
