1. 1. URBAN SEGREGATION AND URBAN FORM : From residential segregation to segregation in public space

   Författare :Ann Legeby; Lars Marcus; Eva Öresjö; Anna-Johanna Klasander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban segregation; urban form; urban design; housing segregation; residential segregation; public space; co-presence; public life; spatial affordance; Architecture; Arkitektur;

   Sammanfattning : Urban segregation is considered a major social problem in Sweden and several national anti-segregation initiatives have been launched to decrease social and ethnic segregation but so far only with marginal effects (SOU 2005:29). Urban design and town planning are rarely the focus in national anti-segregation initiatives; the architectural issue has mainly been confined to matters concerning housing policies. LÄS MER

3. 2. Architectural aspects of massive timber : structural form and systems

   Författare :Andreas Falk; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : The hypothesis of this thesis is that there are rational, technical and architectural gains to be made from interactively developed architectural and structural utilisation of massive timber plates. The aim is to study and describe architectural features of structural applications of massive timber and ways to utilise and develop timber-based plates in building applications by combining an architectural and a structural engineering perspective.

4. 3. Computational Methods in Conceptual Structural Design

   Författare :Vedad Alic; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

   Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER

5. 4. Prestress and its application to shell, fabric, and cable net structures

   Författare :Alexander Sehlström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometric stiffness; Form finding; Conceptual design; Stress pattern; Engineering; Prestress; Architecture; Structuraldesign;

   Sammanfattning : Prestressing and shells provide means to create material-efficient and well-functioning structures, as do their combination, offering opportunities for increased material efficiency within the built environment. Prestressing introduces stresses in an object to enhance its performance, and shells include concrete shells, masonry vaults, fabric structures, cable nets, and timber or steel gridshells.

7. 5. Stiffness and vibration properties of slender tensegrity structures

   Författare :Seif Dalil Safaei; Gunnar Tibert; René Motro; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tensegrity booms; Tensegrity grids; Tensegrity power lines; Finite element analysis; Genetic algorithm; Flexibility analysis; Form-finding; Pre-stress design; Optimization;

   Sammanfattning : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. LÄS MER
