Rezumat
Brancusi’s Endless Column is an interesting case study in bluff body aeroelasticity. It has been referred to as aeroelastically indifferent owing to its remarkable aerodynamic view of the column behavior is incomplete, and that the structural dynamics characteristics of the column have a powerful role in ensuring its aeroelastic stabilty. The calculations show that the column’s design, which provided for significant damping and mass, would assure its aeroelastic stability even if the column had a conventional and aeroelastically less favorable shape, i.e. if it were a circular cylinder (a shape that is unfavorable from the point of view of vortex induced response or a square cylinder ( a space that is unfavorable from the point of view of galloping)
