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. Human-structure interaction effect on the dynamic response of footbridges : An analytical and experimental study
Sammanfattning : Lightweight, slender and lightly damped footbridges are often susceptible to HumanInduced Loads (HILs) when pedestrian step frequencies coincide with the naturalfrequencies of the structure. For vertical vibrations, this can compromise the serviceabilitylimit state of the system. LÄS MER
3. 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
4. Towards intuitive interfaces
Sammanfattning : Operators like fighter pilots, combat vehicle drivers and fire and rescue command operators handle considerable amount of information during mission critical activities. The increasing complexity of the information landscape calls for alternative information presentation. LÄS MER
5. Numerical modeling of train-induced ground vibrations
Sammanfattning : The population is growing, and an increasing proportion of the population live in urban areas. As a consequence, human exposure to noise and vibrations is increasing. Larger and denser cities lead to a higher amount of traffic close to where people work and live. LÄS MER
