2. 1. Fatigue of steel bridges : New structural details and the implementation of high strength steel

   Author : Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high strength steel; fatigue; steel bridges; steel and concrete composite bridges; new structural details; linear elastic fracture mechanics; effective notch stress method; nominal stress method; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

5. 3. Environmental preferences among steel stakeholders

   Author : Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

   Abstract : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. READ MORE

6. 4. A Study on Structural Cores for Lightweight Steel Sandwiches

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

   Abstract : 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.
