  2. 1. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

    Author : Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

  4. 2. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

  5. 3. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

    Author : Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element modelling; alternative load paths; cross laminated timber; progressive collapse; CT scanning; fibre reconstruction; image analysis; Träteknik; Wood Science and Engineering;

    Abstract : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. READ MORE

  6. 4. Studies on the competitiveness of wood : - market segmentation and customer need assessments

    Author : Ragnar Jonsson; Roger Cooper; Växjö universitet; []
    Keywords : wood; building material; material substitution; end-consumer; floorcovering; customer needs; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Over the last decades, wood has encountered increasing competition from other building materials. Hence, it is relevant to study the underlying factors of material substitution. The market for repair and remodelling (R&R) is growing in importance. READ MORE

  7. 5. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    Author : Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

    Abstract : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. READ MORE
