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 ... -
Dynamic performance of existing high-speed railway bridges under resonant conditions following a retrofit with fluid viscous dampers supported on clamped auxiliary beams
Elsevier (2014-02)This contribution investigates the application of Passive Control techniques to reduce the severe transverse vibrations that railway bridges of moderate lengths may experience under resonant conditions. The proposed solution ... -
Dynamic performance of existing high-speed railway bridges under resonant conditions retrofitted with fluid viscous dampers
Elsevier (2010)This paper deals with the application of Passive Control techniques to mitigate the excessive vibrations that short simply supported railway bridges may undergo under the circulation of High-Speed trains. A possible solution ... -
Effect of soil properties on the dynamic response of simply-supported bridges under railway traffic through coupled boundary element-finite element analyses
Elsevier (2018-09-01)Railway induced vibrations on short-to-medium span simply-supported (SS) bridges is addressed in this contribution. Such structures may experience high levels of vertical acceleration at the platform, leading to adverse ... -
On the basic phenomenon of soil-structure interaction on the free vibration response of beams : Application to railway brigdes
Elsevier (2016-10)The dynamic transverse response of beam type bridges under railway traffic is addressed in this contribution. In particular, how soil-structure interaction may affect the critical or resonant velocities and the associated ... -
Resonance and cancellation phenomena in two-span continuous beams and its application to railway bridges
Elsevier (2020-11-01)The objective of this study is to evaluate the vibratory response of two-span continuous beams subjected to moving loads and, in particular, to investigate the maximum resonance and cancellation of resonance phenomena. The ... -
Transverse vibrations in existing railway bridges under resonant conditions: Single-track versus double-track configurations
Elsevier (2010)In this paper, the dynamic performance of a certain kind of existing bridge under the action of high-speed railway traffic is addressed. Short-to-medium-span simply supported structures are susceptible to experiencing ... -
