“…The effect of capillary hysteresis, which occurs due to surface tension, is significant only for very small liquid containers and is thus often neglected during liquid damper design. Free-surface contamination refers to the viscosity effect at and in the neighborhood of the free liquid surface caused by the viscoelastic surface film (Miles, 1967; Storey and Kirk, 2020). Viscous stresses in the liquid interior are developed by molecular diffusion when fluid molecules move into a region of fluid with a different velocity (Glegg and Devenport, 2017).…”

Passive tuned liquid dampers, being cost-effective, easy to implement, and reliable structural vibration control devices, have received significant attention from designers and researchers. Considerable works devoted to the extraction of higher damping, increase in volumetric efficiency, improvement in architectural adaptability, and use in a large spectrum of structures have led to the development of a variety of configurations of passive tuned liquid dampers. Rigorous research efforts are being devoted to the utilization of different forms of tuned liquid dampers for the vibration control of buildings, bridges, chimneys, wind turbines, etc. However, till now, only a few varieties of tuned liquid dampers have been implemented in real-life structures, while the others require further refinement. This necessitates the present work, through which a systematic review on tuned liquid dampers of various configurations for structural response reduction is presented, with a focus on the design of the dampers. To organize the review in a structured manner, the large family of tuned liquid dampers is categorized into five groups based on their energy dissipation mechanism, namely the tuned sloshing damper, tuned liquid column damper, combined tuned sloshing damper-tuned liquid column damper system, compliant liquid damper, and liquid damper with submerged tuned oscillator. The modeling, analysis, design, and performance-related aspects of the different varieties of tuned liquid dampers are covered. The advantages and applicability of the different types of tuned liquid dampers are highlighted along with their real-life installations. The current gaps in the development of the various tuned liquid damper configurations and scope of future developments are also identified.

“…Thin-walled spherical shell structure is widely used in aerospace [1], deep-sea engineering [2], defense industry [3] fields, such as the return capsule [4], manned submersible [5], rocket fuel storage tanks [6], satellite antenna [7] and so on. To ensure the service performance of the thin-walled spherical shell structure, the shell wall thickness requirements are extremely stringent, usually requiring precision milling [8].…”

Thin-walled spherical shells are weakly rigid and prone to clamping deformation under clamping force, which will affect machining accuracy. In this paper, the support-absorption composite clamping method is proposed and the in-situ conformal clamping strategy is obtained through the deformation coordination optimization. Firstly, the thin-walled spherical shell static response model is established, and the displacement analytic solution of equivalent constraint superposition is proposed by decoupling load and boundary constraint and Reisner's force-displacement hybrid method. Then, the vacuum generation of the Laval nozzle and pressure regulation mechanism is elucidated, and the matching mechanism of vacuum degree and spring support is revealed. Considering the support and adsorption deformation coordination optimization, the in-situ conformal clamping model is constructed. Next, the simulation explores the response of thin-walled spherical shells at different positions and adsorption effects on different wall thicknesses. The applied velocity ratio of the load in in-situ conformal clamping is analyzed. Finally, comparative experiments with different clamping methods are carried out and the results show that: Larger deformation in the top ± 10° range. The average prediction error of the theoretical model is 11.97%. With a larger load, the larger deformation, and recommended to control within 0.5Mpa. A larger number of partitions isn't recommended, nonlinearities could cause larger acceleration mutations. The thinner the thickness or the smaller the support load, the support-adsorption composite clamping effect is more obvious, the maximum can reduce the clamping deformation by 64.3%. In-situ conformal clamping method can reduce the deformation of the clamping process by 33.3%.

To obtain the seismic performance of plate-shell integrated concrete liquid-storage structures (PSICLSS), a scale test model was built for shaking table testing. A combination isolation layer is proposed, and the dynamic responses of non-isolation and combination isolation PSICLSS under unidirectional and bidirectional earthquakes were tested. The results show that the combination isolation layer can change the spectral characteristics of the input acceleration, reducing the acceleration response and displacement of the structure, but it will increase the hydrodynamic pressure and liquid sloshing height. Under earthquake action, the liquid sloshing of combination isolation PSICLSS clearly appears as a nonlinear splash phenomenon. When considering the vertical earthquake, the horizontal acceleration response of PSICLSS and the liquid sloshing height change little, the peak hydrodynamic pressure changes significantly, and the peak position also changes. The maximum displacement of the isolation layer increases, but the residual displacement decreases.
