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

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Kirsi Jarnerö; Linnéuniversitetet.; RISE.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Byggteknik; Civil engineering; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance;

    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. Vibration transmission in lightweight buildings : Numerical prediction models

    University dissertation from Structural Mechanics, Lund University

    Author : Ola Flodén; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016-12-22]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration transmission; structure-borne sound; wood buildings; numerical modelling; finite element method; structure-acoustic coupling; model validation; model calibration; dynamic substructuring; model order reduction;

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

  3. 3. Vibration-based Assessment of Tensegrity Structures

    University dissertation from KTH Royal Institute of Technology

    Author : Nasseradeen Ashwear; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity; Pre-stress; Vibration; Health monitoring; Buckling; Temperature effect; Vibration health monitoring VHM; Optimization; Teknisk mekanik; Engineering Mechanics;

    Abstract : Vibration structural health monitoring (VHM) uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life.The whole function, expressed by stiffness and frequencies of tensegrity structures are primarily related to the level of pre-stress.

    Abstract : A rapid growth of installed wind power capacity is expectedin the next few years. However, the siting of wind turbines ona large scale raises concerns about their environmental impact,notably with respect to noise. READ MORE

  5. 5. Vibration Frequencies as Status Indicators for Tensegrity Structures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nasseradeen Ashwear; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity; Pre-stress; Vibration; Health monitoring; Buckling; Temperature effect; Vibration health monitoring VHM; Tensegritet; Förspänning; Vibration; Hälsokontroll; Knäckning; Temperatureffekt; Vibrationsbaserad hälsokontroll; Teknisk mekanik; Engineering Mechanics;

    Abstract :  Applications of vibration structural health monitoring (VHM) techniques are increasing rapidly. This is because of the advances in sensors and instrumentation during the last decades. VHM uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life. READ MORE
