1. Raising allowable axle loads on railway bridges using simulation and field data
Sammanfattning : .... LÄS MER
2. Influence of wheel tread damage on wheelset and track loading – Field tests and numerical simulations
Sammanfattning : Wheel tread damage leading to high magnitudes of vertical wheel–rail contact forces is a major cause of train delays in the Swedish railway network, in particular during the coldest months of the year. According to regulations, vehicles generating contact forces exceeding the limit value for allowed wheel–rail impact loads must be taken out of service for wheel maintenance. LÄS MER
3. Upgrading concrete bridges : post-tensioning for higher loads
Sammanfattning : There are a great number of old structures around the world, some of which were designed for completely different purposes than in their current application. Swedish railway bridges were for example only designed for maximum axle loads of 200 kN in the beginning of the 20th century, while the highest axle loads of today are twice as high. LÄS MER
4. Application of monitoring to dynamic characterization and damage detection in bridges
Sammanfattning : The field of bridge monitoring is one of rapid development. Advances in sensor technologies, in data communication and processing algorithms all affect the possibilities of Structural Monitoring in Bridges. LÄS MER
5. Study and Application of Modern Bridge Monitoring Techniques
Sammanfattning : The field of monitoring is one of rapid development. Advances in sensor technologies, in data communication paradigms and data processing algorithms all influence the possibilities of Structural Health Monitoring, damage detection, traffic monitoring and other implementations of monitoring systems.
