Shared Tuned Mass Dampers for Mitigation of Seismic Pounding

Rupakhety, Rajesh; Elias, Said; Ólafsson, Símon (MDPI AG, 2020-03-11)

This study explores the effectiveness of shared tuned mass damper (STMD) in reducing seismic pounding of adjacent buildings. The dynamics of STMDs is explored through numerical simulations of buildings idealized as single and multiple degree of freedom ...
Strong ground motion in the epicentral area of the 2020-2021 earthquake swarm in the Reykjanes Peninsula, Iceland

Hernandez, Victor; Rupakhety, Rajesh; Ólafsson, Símon; Bessason, Bjarni; Erlingsson, Sigurdur (Conspress, 2022-09-04)

The Geldingadalur eruption in the Reykjanes Peninsula on 19 March 2021 was preceded by several earthquakes of volcano-tectonic origin throughout 2020 and 2021. Seven earthquakes with magnitude M≥5 took place during the swarm, all of them recorded by ...
Tuned Mass Dampers for Response Reduction of a Reinforced Concrete Chimney Under Near-Fault Pulse-Like Ground Motions

Elias, Said; Rupakhety, Rajesh; Ólafsson, Símon (Frontiers Media SA, 2020-06-26)

The article investigates response mitigation of a reinforced concrete (RC) chimney subjected to pulse-like near-fault ground motions using tuned mass damper (TMD) schemes. The total height of the chimney is 265 m with a mass of 11,109 ton. Three TMD ...
