1. 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
2. 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
3. Efficient Modelling Techniques for Vibration Analyses of Railway Bridges
Sammanfattning : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges, mainly because high-speed trains can cause resonance in the bridge superstructure. Dynamic simulations, often utilising time-consuming finite element analysis (FEA), have become essential for avoiding such problems. LÄS MER
