... ABSTRACT The active vibration control of a cylindrical shell coupled with complex inner foundations is theoretically investigated using a hybrid analytical-numerical approach. The motion and solution of the shell are described by Flugge theory and wave based method, respectively. Inner...

... ABSTRACT The present paper focus on the effectiveness performance of a MRE damper for vibration control of offshore platform under seismic loadings. MRE materials are fabricated, and a MRE damper in mixing coupling mode is designed. Testing and dynamic modeling of the proposed MRE damper...

..., conductors and pipelines. Many structural failures in these structures are associated with the fatigue damages caused by Vortex Induced Vibration (VIV) (Williamson and Govardhan, 2008; Kamble and Chen, 2016). Various vibration control methods have been then suggested to supress such destructive vibrations...
