This paper investigates the optimized parameters for the tuned liquid column dampers to decrease the earthquake vibrations of high-rise buildings. Considering soil effects, the soilstructure interaction (SSI) is involved in this model. The Tuned Liquid Column Damper (TLCD) is also utilized on the roof of the building. Since the TLCD is a nonlinear device, the time domain analysis based on nonli...

The conventional optimal calibration of a TLCD for suppressing structural vibration is based on the classic 2-degrees-of-freedom (2-DOF) model in terms one specific mode (usually resonant mode). For flexible multi-degrees-of-freedom (MDOF) structures, this implies that background flexibility contribution from other non-resonant modes omitted, resulting an unbalance frequency response structure-...
