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, ...
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)
[Abstract] Most of the water pipe infrastructure is outdated; therefore, frequent maintenance and repair works are required. To speed up the rehabilitation work and to have a more sustainable and efficient approach, ...
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 ...
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 ...
Fail-safe optimum cable system under cable breakage in cable-stayed bridges. Application to the Queensferry Crossing Bridge
(Elsevier, 2023)
[Abstract:] This paper presents a methodology to optimize the cable system in cable-stayed bridges, whose main novelty is to take into account the accidental breakage of one cable within the design process. To this end, a ...
Multi-bubble scheme and structural analysis of a hypersonic stratospheric flight vehicle
(Elsevier, 2022)
[Abstract:] The STRATOFLY MR3 vehicle is the main objective of the STRATOFLY project, which aims to develop a hypersonic air breathing concept capable of covering antipodal routes in less than three hours. The aircraft ...
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 ...
