A stabilized finite element algorithm potential for wind-structure interaction (WSI) problem is presented
in this paper. Streamline upwind Petrov-Galerkin (SUPG) scheme of the large eddy simulation (LES) of
dynamic sub-grid scale (DSGS) is developed under the framework of arbitrary Lagrangian-Eulerian (ALE) description
to solve the governing equations. High stabilization is achieved by a three-step technique in the temporal
discretization. On the other hand, the partitioned procedure is employed for the consideration of the coupled WSI
problem. Newmark integral method is introduced for the computation of structure domain, while spring analogy
method is used for the grid update of the mesh domain. The developed computational codes are applied to the
analysis of wind-induced effect of a spatial latticed structure. The numerical predictions of the three-dimensional
wind flow features, the wind pressures and the wind-induced effect of spatial structures are given. Comparisons
are made between the effects of rigid structure in view of the WSI.
