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 ...
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 ...
Optimum design of cable-stayed bridges considering cable failure
(WIT Press, 2022)
[Abstract:] A methodology to obtain the minimum weight of cables in cable-stayed bridges when a cable fails has been developed. To this end, a multi-model strategy is proposed that takes into account design constraints in ...
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 ...
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 ...
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 ...
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. ...
CFD Applications in Long-span Bridges: An Erasmus+ Traineeship International Mobility Experience
(REDINE, Red de Investigación e Innovación Educativa, 2021)
[Abstract:] An international mobility experience framed within the Erasmus+ Traineeship programme is reported. The topic of the traineeship is related with Computer Science and Engineering, more specifically, CFD applications ...
