On the Aeroelastic Indifference of Brancusi's Endless Column

Published

Rene D. Gabbai

Abstract

Brancusi s Endless Column (T rgu-Jiu, Romania) has been referred to as aeroelastically indifferent owing to its remarkable aeroelastic stability. The column s behavior has been attributed to its unconventional shape. However, calculations presented here indicate that 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 gal-loping).
