1. 16. Design of steel piles for integral abutment bridges

   Författare :Hans Petursson; Ian May; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integral abutment bridges; steel piles; jointless bridges; Steel Structures; Stålbyggnad;

   Sammanfattning : In 1999 research was started at Luleå University of Technology with the purpose to collect experiences from USA and UK on bridges with integral abutments and transfer the experience to Swedish conditions. Since then at least 20 integral bridges with one row of piles under each abutment have been built in Sweden and the European research project INTAB has been completed. LÄS MER

3. 17. A Study on Structural Cores for Lightweight Steel Sandwiches

   Författare :Samuel Hammarberg; Pär Jonsén; Daniel Berglund; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight; Sandwich; Steel; Energy absorption; Homogenization; Finite element; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Lightweight materials and structures are essential building blocks for a future with sustainable transportation and automotive industries. Incorporating lightweight materials and structures in today's vehicles, reduces weight and energy consumption while maintaining, or even improving, necessary mechanical properties and behaviors.

4. 18. The Construction of Construction : The Wenner-Gren Center and the possibility of steel building in postwar Sweden

   Författare :Frida Rosenberg; Timothy Anstey; Helena Mattsson; Timothy Hyde; KTH; []
   Nyckelord :architecture history; architecture technology; Wenner-Gren Center; steel; construction; construction sites; architecture practice; prototype; knowledge production; the Swedish Institute of Steel Construction; postwar Sweden; arkitekturhistoria; arkitekturteknik; Wenner-Gren Center; stål; stålkonstruktion; byggplatser; arkitekturpraktik; prototyp; kunskapsproduktion; Stålbyggnadsinstitutet; svensk efterkrigstid; Architecture; Arkitektur;

   Sammanfattning : The Wenner-Gren Center in Stockholm, built between 1954 and 1966, consists of three buildings dedicated to interdisciplinary and scientific research, designed by Sune Lindström and Alf Bydén of Vattenbyggnadsbyrån (VBB). The project was sponsored by Axel Wenner-Gren, and received support from the Swedish state through the donation of a property at the northern end of Stockholm’s thoroughfare Sveavägen. LÄS MER

5. 19. Passivation of Austenitic Stainless Steel

   Författare :Lena Wegrelius; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; chloride; molybdenum; passivation; hydrochloric acid; nitrogen; ESCA; dissolution;

   Sammanfattning : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). LÄS MER

7. 20. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

   Författare :Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. LÄS MER
