Vibration Amplification of Wooden or Steel Construction Detached Houses Cased by Ground-Borne Vibration

Abstract

Environmental vibration impact on humans in buildings is caused by ground-borne vibration due to rail transit systems, road traffic, construction sites, and industrial plants. To estimate the effect of vibration on humans, it is necessary to measure the tri-axial vibrations in the vertical and horizontal directions in buildings specified in the standards regulated by ISO2631-2:2003. Vibrations in two-and threestory detached houses of wooden or steel construction were measured. The vibration amplifications caused by building structural resonance were evaluated as ratios and level differences in 1/3 octave band vibration accelerations measured at ground near substructure and floors in the 120 houses vibration measurements.

Combined Effects of High-Speed Railway Noise and Ground Vibrations on Annoyance

“…Therefore, these measurements could not provide exact estimates of the vibration exposure to inhabitants in their detached houses. Regardless, according to a recent study concerning the vibration amplitude in wooden or steel detached houses, there was little difference in the vertical vibration between the ground and floors [ 24 ]. Therefore, since the vibration exposure was divided into 5-dB intervals in this study, we expect that the average exposure-response relationships proposed in this study provide good approximations of vertical vibration exposure.…”
