Abstract (EN): This work contributes to a better understanding of the seismic and wind response of cantilevered sign support structures used in highways. For such, the present paper provides a comparative study of the seismic and wind response of a cantilevered sign support (with and without a TMD). The current work begins with a short summary of different methodologies to assess seismic input on structures. Some guidelines on the considered procedure for the selection of ;appropriate suites of accelerograms complying with Eurocode 8-1 prescription for Portugal (Faro) are presented. Complementarily, also is presented a method for generating natural wind histories to be used at the in-service behavior range. To mitigate dynamic effects, the sign support structure is equipped with a TMD with proven efficiency and ease of application and modelling. The structure displays for the out-of-plane direction a significant reduction in terms of displacements and accelerations after the implementation of the TMD for both the seismic and wind cases.
