ABSTRACT
This comparative study aims to present an initial line of study of the optimization of space grid envelope structures for high-rise buildings of circular base, taking into consideration the optimization studies previously analyzed, according to the optimization methodology proposed in relation to the analysis of the isostatic lines for space grid envelope structures for high-rise steel buildings of square or rectangular base. Given the characteristics of this type of geometries or bluff bodies (not aerodynamics or not streamlined bodies) it is necessary to realize studies with boundary layer wind tunnel (BLWT) to model mean flow and turbulent properties of the atmospheric boundary layer (ABL) that are essential for modeling wind flow effects (forces and moments) on buildings and structures, for large numbers of Reynolds, which are typical of the tall buildings proposed. The initial results obtain results that show a better structural efficiency of the steel space grids proposed.
