2. 1. 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

4. 2. 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

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. Evaluation of the Load Carrying Capacity of a Steel Truss Railway Bridge : Testing, Theory and Evaluation

   Author : Jens Häggström; Hans Pétursson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : A good deal of resources has been invested in building and maintaining existing infrastructure.Many structures are now becoming old and do not meet the requirements of an increasingtraffic load, or are reaching the end of their lifecycle. READ MORE

7. 5. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

   Author : Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

   Abstract : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. READ MORE
