Comparison of Vibration Comfort Criteria by Controlled Field Tests on an Existing Long-Span Floor
Problems such as few field tests evidence and irrationality or absence of vibration limits exists in criteria and researches. This experimental study investigated perception thresholds (at the frequency of 5.354 Hz) and the magnitudes of sensation to vibrations caused by an electrical shaker. Linear relationship between vibration magnitude and perception probability has been found. Similar linear relationship exists between mean value of vibration indexes and subject sensation magnitudes. A logarithmic normal distribution of vibration magnitudes causing equal vibration sensation have been found. Limits of criteria are checked, such as ISO 2631/ISO 10137/DIN 4150-2/VDI 2057-1/ATC DG1 et al.
