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

2. Capacity assessment of arch bridges with backfill : Case of the old Årsta railway bridge
Abstract : The work presented in this thesis comprises the assessment of existing arch bridges with overlying backfill. The main objective is to estimate the load carrying capacity in ultimate limit state analysis. A case study of the old Årsta railway bridge is presented, serving as both the initiation and a direct application of the present research. READ MORE

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

4. Concrete Bridges : Improved Load Capacity
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

5. Load-carrying capacity of a strengthened reinforced concrete bridge : Non-linear finite element modeling of a test to failure. Assessment of train load capacity of a two span railway trough bridge in Örnsköldsvik strengthened with bars of Carbon Fibre Reinforced Polymers (CFRP)
Abstract : To meet the future traffic demands there is a constant need of making the infrastructure moreeffective. This can be achieved by increasing the capacity and/or life length of traffic lines. READ MORE
