2. 1. Integrated Bridge Maintenance : Evaluation of a pilot project and future perspectives

   Author : Hans-Åke Mattsson; Håkan Sundquist; Jan Bröchner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge management; bridge maintenance; real service life; partnering; Building engineering; Byggnadsteknik;

   Abstract : The trend in many countries is to outsource maintenance with competitive tendering. The design of the tender is then a crucial issue. A new type of tendering contract, called "Integrated Bridge Maintenance", was introduced in one experimental area in Sweden. READ MORE

4. 2. Integrated structural and construction engineering – A study of project team performance in Swedish bridge design

   Abstract : The Swedish Transport Administration (STA) ambitiously strives to increase the level of productivity and innovation within its operations while meeting and surpassing national sustainability objectives. In this effort, the STA has concluded that climate gas emissions from construction, operation, and maintenance of the infrastructure must be reduced for Sweden to maintain its position as a pioneer and to reach both national and global climate goals.

5. 3. Bridge Edge Beams : LCCA and Structural Analysis for the Evaluation of New Concepts

   Author : José Javier Veganzones Muñoz; Lars Pettersson; Costin Pacoste; Raid Karoumi; Håkan Sundquist; Morgan Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Bridge edge beams in Sweden may involve up to 60% of the life-cyclemeasure costs incurred along the road bridge’s life span. Moreover, usercosts as means of traffic disturbances are caused. Consequently, the SwedishTransport Administration started a project to find better alternativeedge beam design proposals for the society. READ MORE

6. 4. Bracing of steel bridges during construction; theory, full-scale tests and simulations

   Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

   Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

7. 5. Systematic planning and execution of finite element model updating

   Author : Joakim Wallin; Costin Pacoste; Raid Karoumi; Mario Plos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; finite element model updating; bridge; objective function; updating parameter; mode pairing; dynamik; finita element modelluppdatering; bro; målfunktion; uppdateringsparameter; matchning av moder; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. READ MORE
