摘要/描述

Liquid motions in shallow Tuned Liquid Dampers (TLDs) with rectangular, circular, and annular tanks, subject toharmonic base excitation, are measured experimentally. Using a Single-Degree-of-Freedom (SDOF) Tuned MassDamper (TMD) analogy, equivalent mass, stiffness and damping of the TLD are calibrated from the experimental results.These parameters are functions of the TLD base amplitude. Some important properties of the TLD are discussed on thebasis of these results.
