Increasing Damping Ratios in a Tuned Liquid Damper Using Damping Bars
Key Engineering Materials, 2007Wind-induced vibration of tall buildings have been of interest in engineering for a long time. Wind-induced vibration of a tall building can be most effectively controlled by using passive control devices. The tuned liquid damper(TLD) is kind of a passive mechanical damper, which relies on the sloshing liquid in a rigid tank.

Damping ratio of polynomials with perturbed coefficients
IEEE Transactions on Automatic Control, 1988Let a family of polynomials be (1) \(P(s)=t_ 0s^ n+t_ 1s^{n- 1}+...+t_ n\) where ...

Constant gain stabilization with a specified damping ratio and damped natural frequency
IFAC Proceedings Volumes, 1999Abstract This paper considers the problem of stabilizing a given linear time-invariant plant with a specified damping ratio and damped natural frequency using a constant gain compensator. We show the problem to be solved can be decomposed into two sub-problems.

A time-domain viscous damping model based on frequency-dependent damping ratios
Soil Dynamics and Earthquake Engineering, 2000Abstract This paper introduces the mathematics and procedures used in developing a time-dependent damping model for integration analyses of structural response. To establish the time-dependent viscous damping model, frequency-dependent damping ratios of the structure under a series of steady-state unit impulses corresponding to actual loads are first

Equivalent uniform damping ratios for linear irregularly damped concrete/steel mixed structures
Soil Dynamics and Earthquake Engineering, 2011Abstract Structures consisting of two parts, a lower part made of concrete and an upper part made of steel are investigated. In code-based seismic design of such structures several practical difficulties are encountered, due to inherent differences in the nature of dynamic response of each part.

Strain-Dependent Damping Ratio of Compacted Gravel
2015Compacted gravel is often used as engineered fill to provide required bearing capacity for structures. The dynamic properties of the gravel fill, such as strain-dependent shear modulus and material damping ratio, are required in seismic analyses of these systems.

Estimation of modal damping ratio of impact-damped flexible beams using ANFIS
Neural Computing and Applications, 2012This paper presents the development of adaptive neuro-fuzzy inference systems (ANFIS) model for estimating the modal damping ratio of impact-damped flexible beams. The experimental results obtained from the literature are used as training and testing data for developing the model. Five of six parameters namely the gap, mass, modal amplitude, frequency,
