Detuning of wind-induced vibrations of cooling tower shells

Abstract

Detuning of wind-induced vibrations of cooling tower shells can be achieved through adequately stiff upper edge members. In this case and for double layer reinforcement bending resistance may be sufficient within the usual minimum reinforcement /5/. However, if the cornice stiffness is too weak the required bending reinforcement can exceed the prescribed minimum values by far (Fig. 8). Cracking and thus reduced durability of the cooling tower shell can not be excluded.
