On the Aeroelastic Indifference of Brancusi s Endless Column

Published

Author(s)

Rene D. Gabbai

Abstract

Brancusi s Endless Column (T rgu-Jiu, Romania) is an interesting case study in bluff body aeroelasticity. It has been referred to as aeroelastically indifferent owing to its remarkable aeroelastic stability with respect to galloping. The column s behavior has been attributed to its unconventional shape According to calculations presented in this paper, the column s structural 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 shape unfavorable from the point of view of galloping).
