Abstract:
A new tuned liquid damper device, tuned liquid damperembedded baffles(TLDEB), was proposed to increase energy dissipation through setting transverse baffles in a common tuned liquid damper(TLD)device. The proposed TLDEB was expected to achieve a better control performance for a high-rise building under earthquakes than an common TLD. The equivalent displacement, additional damping ratio and its equivalent linearization of a TLDEB were formulated by using classic potential-flow theory and principle of energy dissipation. A real high-rise building structure was used as a numerical example to demonstrate the damping effectiveness of the proposed TLDEB system subjected to ground random excitation and earthquake wave excitation. The results indicate that TLDEB is capable of improving the structural damping and it has more excellent damping effectiveness than common TLD.
