  1. 1. Vibroacoustic performance of wooden buildings : Prediction and Perception

    University dissertation from Engineering Acoustics, LTH, Lund University

    Author : Juan Negreira; Lunds universitet.; Lund University.; [2016-04-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction tools; Low frequency vibrations; Vibroacoustics; Wooden buildings; Impact sound insulation; Finite element method; Vibration measurements; Flanking transmission; Elastomers; Design indicators; Vibration acceptability; Vibration annoyance; MEMS accelerometers;

    Abstract : 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. READ MORE

  2. 2. Structural-acoustic vibrations in wooden assemblies: Experimental modal analysis and finite element modelling

    University dissertation from Växjö, Sweden : Linnaeus University Press

    Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

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

    University dissertation from Lund University. Department of construction science

    Author : Juan Negreira; Lunds universitet.; Lund University.; [2013]
    Keywords : 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.;

    Abstract : 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. READ MORE

  4. 4. Shear walls for multi-storey timber buildings

    University dissertation from Växjö : School of Technology and Design, Växjö University

    Author : Johan Vessby; Växjö universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; Byggteknik; Civil engineering; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; connections; sheathing;

    Abstract : Wind loads acting on wooden building structures need to be dealt with adequately in order to ensure that neither the serviceability limit state nor the ultimate limit state is exceeded. For the structural designer of tall buildings, avoiding the possibly serious consequences of heavy wind loading while taking account at the same time of the effects of gravitation can be a real challenge.

  5. 5. Moisture Safety in Wood Frame Buildings - Blind evaluation of the hygrothermal calculation tool WUFI using field measurements and determination of factors affecting the moisture safety

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Solof Mundt Petersen; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blind Validation; Moisture Safety; Hygrothermal Calcualtion Tool WUFI; Wood Frame Buildings;

    Abstract : Popular Abstract in Swedish Hårdare krav på lägre energianvändning i byggnader samt ökade energipriser har gjort att välisolerade hus har blivit vanligare. Ökad medvetenhet om koldioxidens påverkan på klimat-förändringarna har också ökat intresset för trähus. READ MORE
