  1. 1. Vibrations in Lightweight Buildings - Perception and Prediction

    Detta är en avhandling från Lund University. Department of construction science

    Författare :Juan Negreira; Lund University.; Lunds universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psycho-vibratory evaluation; Vibrations; Timber floors; Lightweight; Measurements; Serviceability criteria; Vibration annoyance; Vibration acceptability; Elastomer; Finite element method; Prediction Tools.;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : When the Swedish building regulations 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, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. LÄS MER
