Effect of Vinyl Flooring on the Modal Properties of a Steel Footbridge
(MDPI AG, 2019-04)
Damping ratios associated with non structural elements play an important role in mitigating the pedestrian-induced vibrations of slender footbridges. In particular, this paper analyses the effect of vinyl flooring on the ...

Robust improvement of the finite-element-model updating of historical constructions via a new combinative computational algorithm
(Elsevier, 2024-04)
Finite-element-models are usually employed to simulate the behaviour of historical constructions. However, despite the high complexity of these numerical models, there are always discrepancies between the actual behaviour ...

Self-control of a lively footbridge under pedestrian flow
(Víctor Compán Cardiel [etc.], 2015)
In this paper, a case study about a lively footbridge is developed; the vibration levels caused by the pedestrian action are controlled by the change of the modal parameters of the structure due to the pedestrian-structure ...

Estimating robust optimum parameters of tuned mass dampers using multiobjective genetic algorithms
(Víctor Compán Cardiel [etc.], 2015)
Tuned mass dampers (TMD) are a well-known control device widely used to control the vibratory problem originated by the pedestrian action on footbridges. The main purpose of this study is the robust multi-objective ...

Motion-Based Design of Passive Damping Systems to Reduce Wind-Induced Vibrations of Stay Cables under Uncertainty Conditions
(MDPI, 2020-03)
Stay cables exhibit both great slenderness and low damping, which make them sensitive to resonant phenomena induced by the dynamic character of external actions. Furthermore, for these same reasons, their modal properties ...

A direct pedestrian-structure interaction model to characterize the human induced vibrations on slender footbridges
(Consejo Superior de Investigaciones Científicas, CSIC: Instituto Eduardo Torroja, 2014)
Although the scientific community had knowledge of the human induced vibration problems in structures since the end of the 19th century, it was not until the occurrence of the vibration phenomenon happened in the Millennium ...

A crowd-structure interaction model to analyze the lateral lock-in phenomenon on footbridges
(WIT Press, 2018)
In this paper a simplified biomechanical crowd-structure interaction model is proposed and validated in order to analyse the lateral lock-in phenomenon on real footbridges. The proposed crowd-structure interaction model ...

Motion-Based Design of Passive Damping Devices to Mitigate Wind-Induced Vibrations in Stay Cables
(MDPI, 2018-11)
Wind action can induce large amplitude vibrations in the stay cables of bridges. To reduce the vibration level of these structural elements, different types of passive damping devices are usually installed. In this paper, ...

Proposal and calibration of a biodynamic model of human-structure interaction by the resolution of the inverse dynamic problem: application to pedestrian bridges
(2015-12-17)
In this thesis a biomechanical crowd-structure interaction model is proposed and further implemented in order to adequately estimate the energy exchange between pedestrians and footbridge. The proposed model focuses on ...
