Experiences on structural optimization under uncertainty in aerospace components
(WIT Press, 2018)
[Abstract:] Nondeterministic optimization methods have been studied in depth from an academy and industrial point of view. The main drawback when implementing probabilistic optimization methods to complex structures is 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 ...
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. ...
