1. Footbridge Dynamics : Human-Structure Interaction
Sammanfattning : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. LÄS MER
2. 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. LÄS MER
3. 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
4. Systematic planning and execution of finite element model updating
Sammanfattning : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. LÄS MER
5. On the dynamics of footbridges : A theoretical approach and a comparison between running and walking loads
Sammanfattning : The dynamic behaviour of lightweight footbridges is often susceptible to HumanInduced Loads (HILs). Generally HILs are taken into account as moving harmonicfunctions in which the loading frequency represents the step frequency of the pedestrians. LÄS MER
