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 three-story 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.
