Influence of a TMD in ITS control action of a SDOF frame with non-linear hysteretic behavior
| Resumo: | This paper presents a parametric investigation concerning the control parameters of a Tuned Mass Damper (TMD), with the purpose of reducing vibrations of a SDOF frame structure with non-linear hysteretic behaviour, when it is subjected to earthquakes and wind loads. A numerical model (MATLAB/Simulink) is implemented in order to obtain the structural response of a SDOF infilled wall frame structure subjected to two different acceleration signals and evaluate the effectiveness of the applied TMD when the value of its mass is changed. Four different hysteretic behaviour cases will be considered for the infilled wall frame structure. Based on the results obtained, the definition of the mass ratio between the TMD and the main structure will be crucial in finding the ideal performance of a TMD. |
