An equivalent additional damping approach to assess vehicle-bridge interaction for train-induced vibration of short-span railway bridges.
Elsevier (2019-06-01)Constant moving load models are widely adopted in the dynamic analysis of railway bridges under moving trains. However, the use of this simple model may overestimate the resonant response of simply supported bridges if the ... -
H∞ optimization of fluid viscous dampers for reducing vibrations of high-speed railway bridges
Elsevier (2014-04)This work deals with the optimization of fluid viscous damper systems (FVDs) to reduce the resonant dynamic structural response of high-speed railway bridges by algebraic and numerical approaches. The presented method ... -
Influence of the vehicle model on the prediction of the maximum bending response of simply-supported bridges under high-speed railway traffic
Elsevier (2014-08)This investigation intends to contribute to the problem of train-bridge interaction in high-speed railway lines. For design purposes, most often a numerical model based on constant moving loads is used to reproduce the ... -
Retrofit of existing railway bridges of short to medium spans for high-speed traffic using viscoelastic dampers
Elsevier (2012)This paper presents a study on the energy-absorbing capacities of viscoelastic dampers (VEDs) for reducing the resonant vibrations of simply supported high-speed railway bridges of short to medium span. The proposed solution ...
