Abstract
The purpose of this research is to analyze the statics and dynamics of steel smoke

stacks subject to excitation by aerodynamic forces. The wind loads experienced by

smoke stacks arise from various phenomenon, the most prominent of which are static

drag load, vortex shedding, and atmospheric turbulence. The nature of these loading

sources around a cylinder are studied in detail. Both static and dynamic loads are

capable of producing large tip deflections, and are of the most prominent design

criteria for stack designers. A computer program, STACK1, has been created by

modifying an existing analysis code, BEAM8, to be used specifically for stack analysis.

This analysis code utilizes the transfer matrix method to perform detailed bending

and vibration analyses. This new software has been developed to check stack designs

for compliance with appropriate steel stack standards, and provide the designer with

information regarding the static and dynamic response of the structure. A detailed

analysis is performed to demonstrate the validity of approximating a tapered

Timoshenko beam with a series of continuous, constant cross-section beams.
