Abstract: The purpose of this work is to study the nonlinear vibrations induced due to wheel contact. The contact force is nonlinear and is considered to be caused due to a nonpolynomial

Abstract: A design methodology for a variation of the conventional liquid column damper (LCD) (by attaching a spring connection to the LCD) as a seismic vibration control device for structures with nonlinear behavior has been proposed ...

Abstract: An experimental investigation into the passive damping properties of various fluids, including magnetorheological (MR) fluid, in a tuned liquid column damper (TLCD) is undertaken. The coefficient of head loss for different ...

Abstract: A closed-form solution for the optimum tuning ratio of a liquid column damper (LCD) that is valid for damped structures subjected to generalized seismic loading is presented. The closed-form expression is based on the ...

Abstract: An input-output relation for the nonstationary response of long-span bridges subjected to random differential support motions is proposed in the present study. The proposed methodology is more general than the existing ...

Abstract: An investigation into the frequency nonstationarity in the response of primary-secondary (P-S) systems and the impact it could have in the analysis of such structures has been presented in this note. For this purpose, a ...

Abstract: This paper proposes a multiresolution based wavelet controller for the control of linear time varying systems consisting of a time invariant component and a component with zero mean slowly time varying parameters. The real ...

Abstract: A wavelet-based random vibration theory is presented in this paper to predict the stochastic seismic response of a single-degree-of-freedom system. Functions of wavelet coefficients are used to model ground motions as ...

Abstract: This paper presents a statistical measure for the identification of the presence, the location, and the calibration of the strength of singularity in a signal or in any of its derivatives in ...
