Abstract
This paper describes a method for the evaluation of the response of a tall chimney subjected to atmospheric turbulence. Stiffness and mass matrices have been derived using a tapered beam element with three degrees of freedom per node (displacement, slope and curvature). A comparison of two techniques for the calculations of forced response— normal mode and direct formulation—has been made for a simple cantilever beam. It was found that the direct formulation method compared favourably with the normal mode approach. Also, it was found that the element size has an important bearing on the correct representation of pressure fields in cases where these fields are not well correlated along the whole length of the structure.
