1. Train–Bridge Interaction : Literature Review and Parameter Screening
Sammanfattning : 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. LÄS MER
2. Train–Track–Bridge Interaction for the Analysis of Railway Bridges and Train Running Safety
Sammanfattning : In this thesis, train–track–bridge interaction (TTBI) models are used to study the dynamic response of railway bridges. A TTBI model considers the dynamics of the train in addition to that of the track–bridge system. The TTBI model enables the assessment of train running safety and passenger comfort. LÄS MER
3. Simplified dynamic analysis of railway bridges under high-speed trains
Sammanfattning : 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. LÄS MER
4. Optimal design solutions of road bridges considering embedded environmental impact and cost
Sammanfattning : Continuous urbanization and population growth are increasing the demand for transportation infrastructure such as bridges. The construction of these structures represents a significant economic investment for public authorities; moreover, the construction sector accounts for a big portion of CO2 emissions. LÄS MER
