2. 1. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

   Author : Dan Engström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

   Abstract : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. READ MORE

4. 2. On the relation between psychosocial work environment and musculoskeletal symptoms : a structural equation modeling approach

   Author : Pernilla Larsman; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychosocial work environment; felt stress; perceived fatigue; musculoskeletal symptoms; process models; mediation; moderation; structural;

   Abstract : The aim of the present thesis was to investigate the relation between aspects of the psychosocial work environment and musculoskeletal symptoms including the testing of process models of the potential mediating mechanisms of felt stress and perceived fatigue, and the potential moderating mechanism of physical workload. This thesis is based on four empirical studies. READ MORE

5. 3. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

   Author : Markus Peterson; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

   Abstract : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. READ MORE

6. 4. Life Cycle Assessment of Building Products. Case Studies and Methodology

   Author : Åsa Jönsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

   Abstract : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.

7. 5. Modelling and simulation of factors influencing on-site construction of concrete frameworks : Studying the effects of resource allocation, weather conditions, and climate-improved concrete

   Author : Robert Larsson; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-event simulation DES ; Concrete; Structural frames; Productivity; Resource use; Weather; Carbon Emissions;

   Abstract : Concrete is the most common material used to build the structural framework in multistory buildings. However, the construction works carried out on the building site are affected by many different factors that may reduce productivity. READ MORE
