1. Concrete Bridges : Improved Load Capacity
Sammanfattning : 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. LÄS MER
2. Raising allowable axle loads on railway bridges using simulation and field data
Sammanfattning : .... LÄS MER
3. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements
Sammanfattning : Mechanistic-Empirical (M-E) pavement design procedures are composed of a reliable response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic theory (MLET) with improved computational performance by optimizing the time consuming parts of the MLET processes.

4. Analysis of traffic load effects an railway bridges
Sammanfattning : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. LÄS MER
5. Vehicle-Pavement Interaction
Sammanfattning : Several aspects of vehicle-pavement interaction have been studied and discussed in this thesis. Initially the pavement response is studied through a quasi-static and a dynamic computationally efficient framework under moving traffic loads. LÄS MER
