“…Meanwhile, the idea of applying tuned liquid dampers (TLDs) to reduce vibrations in civil engineering structures began in the 1980's (Bauer 1984;Kareem and Sun 1987;Modi and Welt 1987). Since then TLDs, encompassing both Tuned Sloshing Dampers (TSDs) and Tuned Liquid Column Dampers (TLCDs), have become a popular form of supplemental damping system for mitigation of windinduced motions (Fujino et al 1992;Kareem 1990Kareem ,1993Hitchcock and Kwok 1993;Kareem and Tognarelli 1994;Sakai et al 1989;Hitchcock et al 1997;Tait and Isyumov 2007;Vickery 2001).…”

“…Bauer [1] suggested a new damping device consisting of a liquid container filled with two immiscible liquids, in which the motion of the interface is able to dampen the structure effectively. Modi and Welt [2] investigated energy dissipation due to sloshing liquid in torus-shaped notation dampers using the simple potential flow procedure in conjunction with the first-order boundary layer correction.…”

This paper describes the experimental study investigating the suitability of water tank as passive tuned liquid damper for reinforced concrete (RC) structures against earthquake's vibrations. Two 4-storey RC frame structural models with symmetrical in plan and vertical with water tank monolithically attached on top were constructed and tested on uni-axial freedom shaking table with different levels of water in water tank. El Centro earthquake time history 50 % was applied to both structures to investigate the response acceleration and deflection of the structures at fourth floor level. The efficiency of quantity of water has been investigated with reference to response acceleration and deflection recorded by data acquisition software through accelerometers and displacement transducers installed at level of fourth floor of models. It was found that the weight of water 2.5 and 2.0 % weights of structures gave minimum response acceleration and deflection for Model 1 and Model 2, respectively.

“…Several research studies have been conducted on TLDs in the past few decades. The research conducted by Bauer in 1984 [13] proposed a damping device to control vibrations, where a rectangular container filled with two immiscible liquids was utilized, in which the interface motion dissipated the energy effectively. Recently, TLDs have been shown to be effective in lateral vibration control of high-rise buildings.…”

The behavior of a very slender building is investigated under wind loads, to satisfy both strength and serviceability (comfort) design criteria. To evaluate the wind effects, wind tunnel testing and structural analysis were conducted, by two different procedures: (i) Pressure Integration Method (PIM), with finite element modeling, and (ii) High Frequency Force Balance (HFFB) technique. The results from both approaches are compared with those obtained from Eurocode 1 and the Italian design codes, emphasizing the need to further deepen the understanding of problems related to wind actions on such type of structure with high geometrical slenderness. In order to reduce wind induced effects, structural and damping solutions are proposed and discussed in a comparative study. These solutions include (1) height reduction, (2) steel belts, (3) tuned mass damper, (4) viscous dampers, and (5) orientation change. Each solution is studied in detail, along with its advantages and limitations, and the reductions in the design loads and structural displacements and acceleration are quantified. The study shows the potential of damping enhancement in the building to mitigate vibrations and reduce design loads and hence provide an optimal balance among resilience, serviceability, and sustainability requirements.
