Large-Eddy Simulation in wind loading on slender structures
Understanding and predicting the effects of natural wind on a structure is necessary for a safe, effective, and economical engineering design. Experimental techniques are expensive and often provide data that is not sufficiently detailed for the structural engineer. With increasing advances in computational power, it has recently become feasible
to investigate these flows using numerical techniques. Of these, one of the most effective approaches to simulate natural wind is Large-Eddy Simulation (LES). The application of LES to analyse the wind loading, and aeroelastic effects on structures are only a recent venture. This paper reviews the progress made over the last few decades of the analysis of wind flow around slender structures, and the more recent analysis incorporating the effects of freestream turbulence observed in natural wind. Firstly, the physical mechanisms central to wind loading from a renewed perspective is provided in the context of a tall model building; this is followed by an overview the application of LES by the authors to a tall building model. Subsequently, a review is made into the advances in aeroelastic analysis of bridge sections from full-scale observations, wind-tunnel experiments, and Computational Fluid Dynamic perspectives; finally, the recent work by the authors incorporating LES to this application is described.

Abstract
Understanding and predicting the effects of natural wind on a structure is necessary for a safe, effective, and economical engineering design. Experimental techniques are expensive and often provide data that is not sufficiently detailed for the structural engineer. With increasing advances in computational power, it has recently become feasible
to investigate these flows using numerical techniques. Of these, one of the most effective approaches to simulate natural wind is Large-Eddy Simulation (LES). The application of LES to analyse the wind loading, and aeroelastic effects on structures are only a recent venture. This paper reviews the progress made over the last few decades of the analysis of wind flow around slender structures, and the more recent analysis incorporating the effects of freestream turbulence observed in natural wind. Firstly, the physical mechanisms central to wind loading from a renewed perspective is provided in the context of a tall model building; this is followed by an overview the application of LES by the authors to a tall building model. Subsequently, a review is made into the advances in aeroelastic analysis of bridge sections from full-scale observations, wind-tunnel experiments, and Computational Fluid Dynamic perspectives; finally, the recent work by the authors incorporating LES to this application is described.
