Evaluation of TLD Performance in Reducing the Seismic Response of Structures
Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...

متن کاملRectangular and Cylindrical TLDs with Rotatable Baffles to Improve Seismic Behavior of Structures, a Numerical Study
One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...
متن کاملOPTIMIZED TUNED LIQUID COLUMN DAMPERS FOR EARTHQUAKE OSCILLATIONS OF HIGH-RISE STRUCTURES INCLUDING SOIL EFFECTS
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...
متن کاملCOMPARISON OF RELIABILITY BASED AND DISPLACEMENT BASED OPTIMIZATION OF TUNED MASS DAMPERS REGARDING UNCERTAINTY
Some structural control systems have been devised to protect structures against earthquakes, which the tuned mass damper (TMD) being one of the earliest. The effect of a tuned mass damper depends on its properties, such as mass, damping coefficient, and stiffness. The parameters of tuned mass dampers need to be tuned based on the main system and applied load. In most of the papers, the paramete...
