Abstract:A methodology is presented for evaluating, in a life-cycle cost (LCC) perspective, the seismic effectiveness of passive tuned mass dampers (TMDs) on inelastic building structures. Traditional assessment criteria reveal that TMD performance largely depends on the extent of response non-linearity and therefore on the seismic intensity level, proving satisfactory under moderate earthquakes but negligible under strong ones. Yet those criteria cannot provide a concise measure of control advantages, since they canno… Show more
