  1. 1. Assessment of Concrete Structures Including Corrosion and Cracks

    Author : Mattias Blomfors; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; corrosion; nonlinear FE analysis; reinforcement bond; assessment; cracks;

    Abstract : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. READ MORE

  2. 2. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

    Author : Babak Ebrahimi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

    Abstract : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

  3. 3. Assessment of Concrete Bridges : Models and Tests for Refined Capacity Estimates

    Author : Niklas Bagge; Anders Carolin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Optimising the strategy for repairing, upgrading and replacing bridges in the European Union, and elsewhere, is becoming increasingly important due to ageing of the bridge stock, continuously increasing load requirements and budgetary limitations. Thus, there is a clear need to identify or develop, and implement, refined methods for assessing existing bridges in order to determine the most cost-effective options and actions to extend their lives, increase their capacities or replace them.

  4. 4. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Abstract : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. READ MORE

  5. 5. Smart pavement maintenance and infrastructure operation through digital twins : Case study for Norvik Port, Sweden

    Author : Julian Dario Rodriguez; Nicole Kringos; Romain Balieu; Plati Christina; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement management; digital twins; finite element model pavement; infrastructure maintenance.; Vägunderhåll; Digitala tvillingar; Ändliga elementmodeller för vägar; Infrastrukturförvaltning; Civil and Architectural Engineering; Byggvetenskap; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. READ MORE
