Efficient mitigation of high-speed train vibrations on adjacent reinforced concrete buildingsEfficient mitigation of high-speed train vibrations on adjacent reinforced concrete buildings Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2024-05-272022enThe detrimental impact of vibrations on adjacent reinforced concrete (RC) buildings due to high-speed train (HST) passage is investigated in this work. For this purpose, an elaborate numerical model, initially validated with free-field data, has been developed. Subsequently, a 4-story RC building is added at varying distances from track to assess the developing vibrations levels on the structure. Furthermore, an efficient mitigation measure is applied, i.e., single or double trenches filled with expanded polystyrene (EPS) geofoam are placed close to the track, in order to minimize the adverse impact of HST-induced vibrations on residents’ health.This research is co-financed by Greece and the European Union (European Social Fund- ESF) through the Operational Programme “Human Resources Development, Education and Lifelong Learning 2014-2020” in the context of the project “Strengthening Human Resources Research Potential via Doctorate Research – 2nd Cycle” (MIS 5000432).http://creativecommons.org/licenses/by/4.0/Construction and Building Materials314 Lyratzakis Alexandros Λυρατζακης Αλεξανδρος Tsompanakis Ioannis Τσομπανακης Ιωαννης Psarropoulos Prodromos N.
