Dynamic analysis of tall slender structure equipped with passive absorber and founded on various subsoils using simplified model

Popis výsledku v původním jazyce

The paper is focused on the investigation of dynamic behavior of tall slender structures taking into account the soil-structure interaction effect (SSI) and a presence of a tuned mass damper (absorber). The main aim is to qualitatively and quantitativelyassess effects of both phenomena on changes in basic dynamic properties and response of the structure. The real tower equipped with absorber is chosen and analyzed. Analytical and numerical analysis of modal properties and of the response of a simple discrete model are performed. The structure and absorber are represented by one degree of freedom, the interaction interface by spring-dashpot system. This simplified model together with multi degree of freedom discrete model is analyzed parametrically fordifferent dynamic properties of subsoil to cover all possible dynamic effects. The influence of neglecting of both phenomena is quantified and suggestions for assessments of such a type of structures are proposed.
