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, ...
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 ...
Efficient Modal-Based Method for Analyzing Nonlinear Aerostatic Stability of Long-Span Bridges
(Elsevier, 2021)
[Abstract] An efficient method for analyzing the nonlinear aerostatic stability of long-span bridges using a modal formulation is proposed. First, a simplified linear version defined as modal-based approach is introduced, ...
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 ...
Wave Celerity in Hydraulic Transients Computation for CIPP-Rehabilitated Pipes
(WIT Press, 2020)

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 ...
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 ...
