Effect of monopile-soil interaction on performance of negative stiffness-assisted compliant liquid dampers-inerter designed for offshore wind turbine towers

Applied Ocean Research
Previous research has shown that compliant liquid damper-inerter (CLDI) systems, especially with a negative stiffness (NS) element, effectively reduce vibrations of monopile-supported offshore wind turbine towers (MOWTTs) exposed to multiple hazards ...
