1. Slab Frame Bridges : Structural Optimization Considering Investment Cost and Environmental Impacts
Abstract : This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge.

2. Modelling the acoustic performance of slab tracks
Abstract : Transport is a major contributor to anthropogenic greenhouse gas emissions. Railway transport has a small footprint compared to other means of transport. This is one reason for the construction of new high-speed railway lines world-wide. READ MORE

3. Slab track optimisation considering dynamic train–track interaction
Abstract : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. READ MORE

4. Simulation of vertical dynamic interaction between railway vehicle and slab track
Abstract : The usage of slab track for high-speed railway lines has increased in recent decades. In Sweden, the building of new railway lines for higher speed and the selection of track design for such lines are currently being debated. READ MORE

5. Simulating rolling noise on ballasted and slab tracks: vibration, radiation, and pass-by signals
Abstract : Shifting to rail-bound freight and passenger traffic is key in Europe's strategy towards transport decarbonisation. However, increasing railway traffic can increase environmental noise pollution. Rolling noise is often the dominant noise source. It originates from the interaction of the rough running surfaces of wheel and rail. READ MORE
