1. 1. 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.

3. 2. The Absent Meaning of Concrete Form in Theory of Architecture

   Författare :Cecilia Häggström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; body; aesthetic theory; architecture; practical knowledge; artifacts; environmental theory; building function; architectural theory; phenomenology; aesthetic theory;

   Sammanfattning : The aim of this dissertation is to discuss architecture as forming practical conditions for our way-of-being, and to clarify that which prevents traditional theory of architecture from dealing with these practical conditions as such. The dissertation investigates a theoretical problem concerning the nature of the relation between human being and the built environment. LÄS MER

4. 3. Hydrophobic Impregnation of Concrete Structures : Effects on Concrete Properties

   Författare :Anders Selander; Johan Silfwerbrand; Jan Trägårdh; Mårten Janz; Andreas Gerdes; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. LÄS MER

5. 4. Differential geometry and structural action of vaults and shells

   Författare :Emil Adiels; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Masonry vaults and bridges, concrete shells, and steel and timber grid shells are all examples of shell structures. Their beauty, spatial qualities, structural efficiency and manufacturing are closely tied to their geometry. LÄS MER

7. 5. An Algorithmic Framework for Intelligent Concrete Structural Defects Detection and Classification

   Författare :Ali Mirzazade; Björn Täljsten; Cosmin Popescu; Thomas Blanksvärd; Diogo Rodrigo Ferreira Ribeiro; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil Engineering Structures; defect detection; Structural Health Assessment; Bridge Inspection; Computer Vision; Point-Cloud Generation; Severity Assessment; Machine Learning Regression; Bridge 3D Modeling; Unmanned Inspections; Byggkonstruktion; Structural Engineering;

   Sammanfattning : The primary objective of inspecting concrete civil structures is to gather information concerning the deterioration of concrete elements, including issues like concrete cover cracking, delamination, or corrosion. Typically, this data is documented through field inspection notes, hand-drawn sketches, and photographs. LÄS MER
