Vibrations in Lightweight Buildings - Perception and Prediction
When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. In lightweight constructions using timber floors, vibrations can cause some nuisances for the inhabitants and complaints are often reported. Still, no vibration limits are given in any international standard due the complexity involved, simply certain guidelines and guide values being suggested instead. The vibrational response of wooden buildings has therefore become an issue to be tackled during their design phase. The aims of the present Licenciate dissertation can in general terms be divided into two basic categories: the development of indicators of human exposure to floor vibrations, and the development of numerical prediction tools for the verification of vibratory and acoustic performance before a building is actually put up. The appended publications Paper A and Paper B, aimed at supplementing the lack of existing studies addressing human response to floor vibrations. In order to obtain a better estimate of an acceptable level of vibrations in dwellings, measurements on real floors while people walked on the them, as well as when they sat down while another person was walking, were performed, measuring the accelerations, velocities and deflections they were exposed to. Indicators of human response to vibrations were extracted by determining relationships between people's answers to questionnaires about their perception and experience of the vibrations, and different parameters as determined by measurements. Several indicators were found to describe people's answers to questions both regarding vibration annoyance and vibration acceptability. Also, the applicability of several serviceability criteria found in the literature was ...
