Wind-induced response of soil-structure-damper systems

The wind-induced motion of tall/slender structures equipped with tuned mass dampers was investigated, taking into account the effect of soil compliancy under the footing. A transfer matrix formulation was used to analyse the soil-structure-mass damper interaction in the frequency domain. Numerical examples show that soil compliancy will affect structural responses and the effectiveness of tuned mass dampers, depending on the properties of the soil, the properties of the structurem the nature of the excitation and the type of structural response.
