Aerostructural Optimization of Long Span Bridges: Current Advances and Challenges
(ASCE, 2020)
[Abstract] This paper describes the evolution of deck shape of long span bridges since the Tacoma Narrows collapse trying to avoid undesirable aerodynamic behavior under wind flow and the trend in the last decades to ...
Inclusion of Mechanical Dampers in the Multimodal Flutter Analysis of Slender Structures
(WIT Press, 2020)
[Abstract] Sometimes slender structures are reinforced with mechanical dampers to reduce the vibrations caused by aeroelastic phenomena like flutter. However the formulation of flutter analysis only considers the classical ...
Numerical simulations of the aerodynamic response of 2D circular segments by means of URANS
(WIT Press, 2016)
[Abstract:] In the wind engineering field, the so-called D-section (semi-circular cylinder) has attracted some attention from researchers, since it is a galloping prone geometry. In fact, a modest number of references where ...
Experimental and Computational Studies on the Performance of Solar Trackers Under Vortex Shedding, Torsional Divergence, and Flutter
(WIT Press, 2020)
[Abstract] The current development of renewable energies has originated a number of new structural typologies that are the physical support of the energy production systems. Photovoltaic energy is a very mature source and ...
Assessment of the Aerodynamic and Aeroelastic Performance of Long-Span Twin-Box Bridges Based upon Multidimensional Surrogate Models
(MDPI, 2024)
[Abstract:] Twin-box decks are being extensively used in the design of long-span bridges due to their superior flutter performance. Although the significant role played by the gap distance has been previously addressed in ...
Wind tunnel study on the effect of the gap width in the aerodynamic and aeroelastic responses of twin-box decks
(WIT Press, 2018)
[Abstract:] Twin-box decks have recently been introduced in long-span bridges because this type of slotted cross-section provides flutter critical wind speeds higher than mono-box streamlined decks for flexible structures. ...
Numerical simulations of the aerodynamic response of circular segments with different corner angles by means of 2D URANS. Impact of turbulence modeling approaches
(Taylor & Francis, 2018)
[Abstract:] This paper presents the results of numerical and experimental investigations on the force coefficients and Strouhal numbers of circular segments considering different corner angles or chord to sagitta ratios. ...
