SEISMIC RESPONSE CONTROL OF A CANTILEVERED HIGHWAY SIGN SUPPORT, USING A TMD
Journal Title: International Journal of Civil Engineering - Year 2017, Vol 6, Issue 6
Abstract
This work contributes to a better understanding of the seismic response of cantilevered sign support structures, used in highways. For such, the present paper presents a comparative study of the seismic response of a cantilever sign support, when subjected to earthquakes with and without a tuned mass damper (TMD). The paper starts with a brief 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 prescription for Portugal (Faro) are presented. To mitigate earthquakes dynamic effects, the sign support structure can be equipped with a TMD, with proven efficiency, ease of application and modelling, for the out-of-plane vibration control of the sign support, in terms of displacements and accelerations reductions, when the structure is subjected to series of real accelerograms compatible with the earthquake scenario of Eurocode 8-1.

SEISMIC RESPONSE OF TALL BUILDING WITH UNDERGROUND STOREY USING DAMPERS
As the seismic load acting on a structure is a function of the self-weight of the structure, these structures are made comparatively light and flexible, which have relatively low natural damping. Results make the structu...
