Abstract: | A tuned liquid damper (TLD) is nowadays becoming a popular passive device for the vibration suppression of various civil and mechanical structures. Due to the higher convective liquid mass, sloped wall TLD possesses a higher vibration control capacity than its conventional rectangular counterpart. The present study focuses on the vibration control of single-degree-of-freedom (SDOF) structures coupled with sloped wall TLD subjected to horizontal excitations. The potential flow theory is adopted for modeling the liquid sloshing inside the TLD tanks. In order to understand the vibration reduction efficiency near resonance conditions, frequency domain analysis is carried out under a range of excitation frequencies close to the fundamental frequency of the structure. Additionally, the time history analysis is done to demonstrate the vibration reduction efficiency of both types of TLDs under horizontal excitation. A higher vibration reduction efficiency of the sloped wall TLD is observed with less liquid mass than the rectangular TLD. Optimal tuning and mass ratios are determined from the parametric study by changing the liquid quantity |
