Assessment of walking-induced floor vibrations according to the SBR guideline
bookPart
Lightweight floors are prone to high levels of vibration due to human activities. The Dutch building code imposes regulations on floors with respect to safety, health and serviceability. The walking-induced vibrations of floors are not incorporated in these regulations. The private law arrangement in the NEN 6702 (510.5,2) [1] does not completely cover the physical background of the issues and is solely applicable to heavyweight floors with two- or four-sided simply supported or clamped conditions. It merely restricts the first eigenfrequency of a floor to be larger than 3Hz for walking and to be larger than 5Hz for jumping. These restrictions are not sufficient for lightweight floors as these are easily excited by the higher harmonics of (near) periodic loads.
Due to the growing interest in lightweight buildings the need for an appropriate assessment guideline for walking-induced floor vibrations increased. From the need of such a guideline two European research projects, funded by the Research Fund for Coal and Steel (RFCS), were initiated to find the appropriate assessment method [3,4]. This resulted into two guidelines, a European [4] and a Dutch one, namely the SBR guideline for walking-induced floor vibrations [5]. The Dutch guideline describes the complete assessment procedure, while the European guideline only covers the so-called hand calculation method.
In the following the general principles of the (Dutch) guideline are described with an emphasis on the experimental method. Finally, some recommendations are made to
extend and to improve the guideline
