2. 1. Fibre reinforced polymer bridge decks: Sustainability and a novel panel-level connection

   Author : Valbona Mara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Sustainability; LCA; Life-cycle assessment; FRP deck; LCC; Life-cycle cost; Connection;

   Abstract : Fibre reinforced polymer (FRP) bridge decks have emerged as a competitive alternative to traditional decking solutions for the refurbishment of existing bridges, as well as the construction of new ones, in the past two decades. FRP decks offer inherent properties such as light weight, high strength and high resistance to aggressive environments. READ MORE

4. 2. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

   Author : Valbona Mara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

   Abstract : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. READ MORE

5. 3. 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.

6. 4. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

   Author : Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. READ MORE

7. 5. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

   Author : Fatima Hlal; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

   Abstract : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. READ MORE
