  2. 16. 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. 17. 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. 18. Digital Twins for Asset Management of Structures

    Author : Vanessa Saback; Björn Täljsten; Rasmus Rempling; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Twins; BIM; Asset Management; Common Data Environment; Finite Element Modelling; Fiber Optic Sensors; Byggkonstruktion; Structural Engineering;

    Abstract : This thesis deals with asset management of structures through Building Information Modelling (BIM) and Digital Twins.Background: Current inspection and management processes for civil structures are time-consuming and can even be inaccurate. There is an increasingly high potential to improve these processes through recent advances in technology. READ MORE

  6. 19. Re-viewing industrial energy-efficiency improvement using a widened system boundary

    Author : Svetlana Paramonova; Patrik Thollander; Mats Söderström; Stefan Grönkvist; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Improved energy efficiency in industry is important for reaching the targets within the EU strategy for increased sustainability. However, energy efficiency is not always prioritised within companies, and the improvement potential remains large. This paradox called an energyefficiency gap is explained by energy-efficiency barriers. READ MORE

  7. 20. Fatigue evaluation of welded details – using the finite element method

    Author : Mustafa Aygül; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the finite element method; welded details; effective notch stress method; Hot-spot stress method; fracture mechanics;

    Abstract : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.
