Computational Techniques for Novel Design of Long-Span Bridges Considering Aeroelastic Phenomena
(ASCE, 2020)
[Abstract] Optimization techniques have demonstrated their capability to obtain economic and sustainable designs while meeting the performance and safety requirements in a number of engineering disciplines. In the bridge ...
Bridge deck flutter derivatives: Efficient numerical evaluation exploiting their interdependence
(Elsevier, 2015-01)
Increasing the efficiency in the process to numerically compute the flutter derivatives of bridge deck sections is desirable to advance the application of CFD based aerodynamic design in industrial projects. In this article, ...
Verification Approaches for the 3D Static LES Simulations of the Stonecutters Bridge Deck
(WIT Press, 2021)
[Abstract] In computational fluid dynamics (CFD) simulations, verification is the process of identifying both the spatial and the temporal discretisations providing relatively insensitive model results. The underlying goal ...
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 ...
Square Cylinder Under Different Turbulent Intensity Conditions by Means of Small-Scale Turbulence
(WIT Press, 2021)
[Abstract] The phenomenon of turbulence is present in almost every type of flow in practical applications. Depending on its level of intensity and length scale, it can modify both the aerodynamic and aeroelastic performance ...
A Computational Study on the Aerodynamics of a Twin-Box Bridge With a Focus on the Spanwise Features
(Elsevier, 2021)
[Abstract] The wind flow around twin-box decks is particularly complex due to the very important role played by the slot distance between girders and the presence of the downwind box that is immersed in the wake of the ...
Study of a static and vertically free-to-oscillate 4:1 rectangular cylinder by means of 2D URANS simulations
(WIT Press, 2018)
[Abstract:] Flexible structures, such as cable-supported bridges, are prone to suffer from vortex-induced vibrations (VIV) under wind flow, as their span lengths are steadily growing in the last decades. VIV is a phenomenon ...
Aerodynamic performance of twin-box decks: a parametric study on gap width effects based on validated 2D URANS simulations
(Elsevier, 2018)
[Abstract:] 2D URANS simulations are conducted aiming to study the aerodynamic performance under smooth flow of twin-box decks depending on the gap distance between girders. The Stonecutters Bridge is taken as the reference ...
3D LES simulations of a static and vertically free-to-oscillate 4:1 rectangular cylinder: effects of the grid resolution
(Elsevier, 2019)
[Abstract:] In the present study, the aerodynamics of the flow fields around a static and vertically free-to-oscillate 4:1 rectangular cylinder are analysed by means of 3D LES simulations, adopting the OneEqEddy viscosity ...
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 ...
