A NEW STANDARD ON MEASUREMENT, ASSESSMENT AND CLASSIFICATION OF VIBRATIONS FROM LANDBASED TRANSPORT

Protection against vibration nuisance in order to maintain satisfactory vibration conditions during work, sleep, rest and recreation is required in accordance with the European Council Directive on construction products. A new, more functional system for the construction works, the executive work and the control of the building process was therefore introduced in Norwegian building regulations in 1997. Since the ground in many densely populated areas in Norway consists of soft clay with high water content, vibration problems in dwellings from heavy road and rail traffic often occurs. As a qualified vibration measurement method for transport sources was lacking, the work with a new standard, NS 8176, was initiated by several parties involved in these vibration problems. The standard is linked to regulations and guidelines for evaluation of effects of vibrations on human beings in dwellings through the Technical Regulations to the Planning and Building Act 1997 and health legislation. An experimental method for determination of statistical maximum value of velocity or acceleraion and guidelines for assessment of vibrations based on a large number of measurements in Norway, calculations and statistical analysis of data collected in a database was introduced. By means of a national vibro-social survey, the vibration values were related to the people's experiences of degrees of nuisance due to vibrations from transport sources. Results from a similar Swedish sociological study were also assessed. A vibration classification system for buildings based on estimated exposure-effect relationships between human reactions and the statistical maximum velocity or acceleration was provided in four classes (A, B, C and D). The Class C is intended for new dwellings and planning purposes. In a longer time perspective, the vibration problems are in this way expected to be reduced or avoided to a greater extent.
