1. Improved Bridge Evaluation
Sammanfattning : 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. LÄS MER
2. Integrated Bridge Maintenance : Evaluation of a pilot project and future perspectives
Sammanfattning : 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. LÄS MER
3. Bridge Edge Beams : LCCA and Structural Analysis for the Evaluation of New Concepts
Sammanfattning : 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. LÄS MER
4. Evaluation of the Load Carrying Capacity of a Steel Truss Railway Bridge : Testing, Theory and Evaluation
Sammanfattning : 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. LÄS MER
5. I-girder Composite Bridges with Lateral Bracing : Improved load distribution
Sammanfattning : 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. LÄS MER
