Abstract
During the last 2 decades, new code generations have been introduced which incorporate the achieved scientific and technological state of the art that has been proven its usefulness in practical application. The Eurocodes and the CICIND model codes are examples of this development. The Eurocode applies a modified gust response factor to model in-line wind loading and resonance due to turbulence through increasing the peak velocity pressure by a factor which depends on the individual size and dynamic features of the structure considered. The CICIND model codes for steel and concrete chimneys take account of the particular mechanical behaviour and the specific design requirements of these structures and utilizes the mean and the gust wind force, where the gust load defines an equivalent static load scaled to reproduce the real base bending moment of the chimney induced by wind gustiness. The cross-wind excitation of chimneys by vortex shedding is calculated in the CICIND model applying a negative aerodynamic damping to incorporate the motion induced forces, and a bandwidth factor to account for the reduction of the lift force spectrum caused by wind turbulence. Contrarily, the Eurocode relies on an empirical concept. In addition, it contains a further method, where the aerodynamic damping parameter is given for zero turbulence only. The principal issues of the chapter are to identify the merits and the drawbacks of the different concepts and to identify their dominant fields of application.
