1. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques
Abstract : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. READ MORE

2. Train–Bridge Interaction : Literature Review and Parameter Screening
Abstract : New railway lines are continuously being constructed and existing lines are upgraded. Hence, there is a need for research directed towards efficient design of the supporting structures. READ MORE

3. Analysis of traffic load effects an railway bridges
Abstract : 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. READ MORE

4. Simplified dynamic analysis of railway bridges under high-speed trains
Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE

5. Railway bridge response to passing trains : Measurements and FE model updating
Abstract : Today’s railway bridges are analysed in more detail for moving loads due to the increase in speeds and axle loads. However, these numerical analyses are very time consuming as they often involve many simulations using different train configurations passing at different speeds and many considerations to take into account.
