21. Structural Earthquake Response Analysis
Sammanfattning : AbstractEarthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. LÄS MER
22. Flexible culverts in sloping terrain : Research advances and application
Sammanfattning : Although the construction of flexible culverts involves simplicity in comparison to similar concrete structures, the complexity of the beneficial interaction between soil and steel materials requires good understanding for their composite action and performance. Current design methods have certain validity limitations with regard to applicable slopes above the structures. LÄS MER
23. Ground vibrations due to pile and sheet pile driving : influencing factors, predictions and measurements
Sammanfattning : Ground vibrations due to pile driving are part of a complex process. Vibration is generated from the pile driver to the pile. As the pile interacts with the surrounding soil, vibrations are transferred at the pile-soil interface. The vibration propagates through the ground and interacts with structures, both above ground and underground. LÄS MER
24. 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
25. Modeling flow and sediment transport in water bodies and watersheds
Sammanfattning : The research focus is on the various modeling aspects of flow and sediment transport in water bodies and watersheds. The interaction of flow with a mobile bed involves a complex process in which various turbulent scales characterized by coherent structures cause a chaotic sediment motion. LÄS MER
