2. 21. On the Uptake of Energy Efficiency Technologies in European Residential Buildings

   Author : Clara Camarasa; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Europe; measures; residential building stock; technology; energy efficiency;

   Abstract : Residential buildings constitute approximately 75% of the European building stock, accounting for circa 30% of the EU´s overall energy demand and emissions. They also represent one of the biggest sources of energy saving potential, holding a crucial role in achieving EU carbon targets. READ MORE

5. 23. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction

   Author : Jens Bergenudd; Jean-Marc Battini; Roberto Crocetti; Patricia Hamm; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic analysis; Modal analysis; Pedestrian bridge; Timber; Railings; Asphalt; Slip modulus; Finite element modelling; Dynamisk analys; Modal analys; Gång- och cykelbro; Trä; Räcken; Asfalt; Förskjutningsmodul; Finita element modellering.; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Abstract : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. READ MORE

6. 24. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

   Author : Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; KTH; []
   Keywords : Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Abstract : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

7. 25. Capacity assessment of arch bridges with backfill : Case of the old Årsta railway bridge

   Author : Andreas Andersson; Håkan Sundquist; Raid Karoumi; Clive Melbourne; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete arch bridge; soil backfill; spandrel walls; field measurements; finite element method; load distribution; ultimate limit state.; Betongbågbro; jordfyllning; sidomur; fältmätningar; finita element metoder; lastspridning; brottgränstillstånd.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : The work presented in this thesis comprises the assessment of existing arch bridges with overlying backfill. The main objective is to estimate the load carrying capacity in ultimate limit state analysis. A case study of the old Årsta railway bridge is presented, serving as both the initiation and a direct application of the present research. READ MORE
