Efficient mitigation of high-speed train vibrations on adjacent reinforced concrete buildings
Graphical abstract Display Omitted
Highlights Assessment of adjacent RC buildings response due to HST-induced vibrations. Numerical model validation with free-field data at the frequency range of interest. Vibrations are higher at closer track distances and increase along building height. Efficient mitigation of HST vibrations using single or double EPS-filled trenches. Double trenches reduce more HST vibrations, close to health protection limits.
Abstract The 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.
