Query: Framework for a simulation-based aerodynamic shape optimization of
  bridge decks for different limit state phenomena   Wind-induced response governs the design of the long-span bridges. The shape
of the deck is one of the most important factors that not only affects the
mechanical properties but greatly influences the aerodynamic performance of the
bridge. An efficient framework is proposed to perform aerodynamic shape
optimization of a bridge deck using Computational Fluid Dynamics (CFD)
simulations and response surface strategies considering aeroelastic phenomena
such as flutter, buffeting and Vortex-induced Vibrations (VIV). A parameterized
cross section of the deck has been utilized ensuring required carriageway width
and structural demand. The Particle swarm optimization algorithm has been
employed which leads to an optimized shape that performs better as compared to
the reference section. The presented aerodynamic shape optimization framework
has a great potential to be used in the design of long-span bridges.
