1. 1. On the Load Distribution and Design of a Chain Drive

   Författare :Ingvar Troedsson; Maskinelement; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. LÄS MER

3. 2. Physical load, psychosocial and individual factors in visual display unit work

   Författare :Jens Wahlström; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer work; musculoskeletal symptoms; working; technique; psychosocial factors; physical load; muscular tension; mental; stress;

   Sammanfattning : The overall aim of this thesis was to explore associations between physicalload, psychosocial and individual factors in visual display unit (VDU)work. Furthermore, the aim was to investigate whether perceived musculartension is a predictor of neck pain among VDU operators. LÄS MER

4. 3. On the long-term behaviour of tension loaded piles in natural soft soils

   Författare :Jorge Yannie; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

   Sammanfattning : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. LÄS MER

5. 4. In-plane tension behaviour of masonry

   Författare :Miklos Molnar; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

   Sammanfattning : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. LÄS MER

7. 5. Effects of Steel Fibres on Cracking in Reinforced Concrete

   Författare :Anette M Jansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uniaxial tension test; Keywords: Self-compacting; characteristic crack width; fibre-reinforced; bond; tension stiffening; Digital Image Correlation; pull-out test;

   Sammanfattning : ABSTRACTAlthough it is well known that fibre reinforcement acts as a crack arresting agent, there is still a need for deeper knowledge of the actual cracking behaviour, especially regarding cracks with widths smaller than 0.3mm. LÄS MER
