  1. 1. Vibrations in timber floors Dynamic properties and human perception

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Kirsi Jarnerö; Anders Professor; Tomi Toratti; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

    Abstract : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. READ MORE

  2. 2. Probabilistic System Effects in Timber Structures

    University dissertation from Division of Structural Engineering Lund Institute of Technology Lund University

    Author : Martin Hansson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Abstract : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. READ MORE

  3. 3. Low Frequency Impact Sound in Timber Buildings Simulations and Measurements

    University dissertation from Division of Structural Engineering Lund Institute of Technology Lund University

    Author : Jörgen Olsson; Andreas Linderholt; Leif Kari; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-frequency; impact sound; light weight floor; timber joist floor; tapping machine; multi-storey timber building; frequency response functions.; Stegljud; Byggteknik; Civil engineering;

    Abstract : An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. READ MORE

  4. 4. Development of prefabricated timber-concrete composite floors

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Elzbieta Lukaszewska; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. READ MORE

  5. 5. Complexity and learning in timber frame housing the case of a solid wood pilot project

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ylva Sardén; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : An extensive governmental evaluation of the Swedish construction industry shows that it is possible to reduce production costs in housing construction through industrialisation, customer orientation, and a more efficient construction process. Today large construction companies are more and more focused on dealing with systems and coordinating large projects and the real production is getting less important. READ MORE
