  1. 1. 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

  2. 2. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

    Author : Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. READ MORE

  3. 3. Assessment of existing concrete bridges : bending stiffness as a performance indicator

    Author : Markus Bergström; Paulo J. de S. Cruz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Optimizing the use of existing civil reinforced concrete (RC) structures could be interpreted in such a way as to say that the capacity should be used and taken care of in an effective manner, both from a technical and economical point of view, keeping the safety in mind. Achieving this requires thorough understanding of the structure and also of the tools used for assessing current and future capacity and needs. READ MORE

  4. 4. Structural Analysis of Existing RC Bridge Deck Slabs Structural Analysis of Existing RC Bridge Deck Slabs

    Author : Jiangpeng Shu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-carrying capacity; assessment; Reinforced concrete RC bridge deck slabs; structural behaviour; Finite element FE analyses;

    Abstract : Due to ageing of the bridge stock, continuously increasing load requirements, the need for assessing existing bridges is becoming increasingly important. Reinforced concrete (RC) bridge deck slabs are among the most critical parts to the load carrying capacity of bridges. READ MORE
