Abstract
Consideration of vortex shedding response is important for high-rise chimneys when air flow causes strong vibrations of the structure in a certain range of wind speeds when the frequency of natural vibrations of the structure coincides with the frequency of Karman vortex shedding. Among the methods of protection against vortex shedding response, for example, the use of dampers, but the most interesting results show the optimization of enclosing constructions of high-rise chimneys, capable of reducing the amplitudes of lateral forces of wind effects caused by vortex shedding. Therefore, in this research, a study of the applicability of lattice enclosing constructions to protect high-rise chimneys from vortex shedding response by reducing the amplitude of wind effects is considered.
