  2. 1. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges

    Author : Louise Andersson; Johan Silfwerbrand; Anders Selander; Ylva Edwards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge maintenance; preventive maintenance; chloride ingress; high-pressure washing; Concrete Structures; Betongbyggnad;

    Abstract : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

  4. 2. Improved Bridge Evaluation

    Author : Hendrik Schlune; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model updating; structural identification; Bridge evaluation; concrete structures; finite element analysis; finite element method; load cases;

    Abstract : Accurate structural models are required for optimal management of existing bridges and economical new ones. However, unavoidable modelling uncertainties and difficulty in modelling the non-linear response of concrete bridges can lead to structural models which do not fulfil this requirement. READ MORE

  5. 3. Concrete Bridges : Improved Load Capacity

    Author : Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

  7. 5. 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
