Objective. The purpose of the study is to determine the current requirements for vibration regulation in buildings.
Object and methods of the study. Standards: ISO 2631-1:1997; ISO 2631-2: 2003; DSTU ISO 2631-1:2004; DSTU ISO 2631-2: 2004; BS 6472-1:2008; ONORM S 9012:2010 (Austria); DIN 4150-2:1999 (Germany); UNI 9614:1990 (Italy); Japan: Vibration Control Law; SBR Richtli - Deel B 2002 (Netherlands); NS 8176:2005 (Norway); Real Decreto 1307/2007 (Spain); SS 4604861:1992 (Sweden); FRA (2005), FTA, 2006 (USA).
Research results and discussion. The main parameters of vibration, thresholds of sensitivity and comfort, vibration evaluation criteria (VDV, eVDV), directions of action of general vibration, frequency weighting curves (Wb, Wd, Wm), the probability of complaints at different values of vibration acceleration, desirable and maximum weighted average values of vibration acceleration for continuous and impulsive vibration in buildings were analyzed. The current DSTUs on vibration in buildings in Ukraine are analyzed. It was found that these standards are outdated (old coordinate systems and old values of the coefficients of frequency weighting curves are used). It was found that there are no standards for permissible levels or values of vibration in buildings for humans in Ukraine.
Conclusions. As a result of the analysis of the considered standards, it was found that the main parameters of vibration are: vibration displacement, vibration velocity; vibration acceleration. Vibration acceleration is most often used. Vibration perception thresholds are not consistent with existing standards, which use frequency weighting factors that do not sufficiently take into account human sensitivity. In different countries, limit value criteria are set above the perception thresholds. Some of them are derived from the threshold irritation level. Vibration criteria are based on maximum and average values. The former are more related to sleep disturbance, the latter are more related to irritation.
