XFEM crack growth virtual monitoring in self-sensing CNT reinforced polymer nanocomposite plates using ANSYS
(Elsevier, 2022-03)
This paper presents an eXtended Finite Element Method (XFEM)-based numerical scheme to compute electrical resistivity changes caused by the presence of cracks and the crack growth. Using the commercial finite element package ...

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 ...
