1. Bridge Overhang Slabs with Edge Beams : LCCA and Structural Analysis for the Development of New Concepts
Abstract : Bridge edge beams are associated with high life-cycle costs because of the need of maintenance, which also causes traffic disturbances. For this reason, the Swedish Transport Administration started a project to find better solutions. One of the proposals was a design without edge beam. READ MORE

2. Reliability-based design of rock tunnel support
Abstract : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. READ MORE

3. Improving the Dynamic Design Philosophy of High-Speed Railway Bridges Using Reliability-Based Methods
Abstract : Modern railway infrastructures, especially bridges, are exposed to significant vibrations with potential safety implications. In this context, previous studies have shown the inconsistency and inadequacy of some conventional design methods necessitaing them to be improved. The assessment of safety inherently deals with uncertainties. READ MORE

4. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests
Abstract : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

5. Strengthening of concrete structures by the use of mineral based composites : system and design models for flexure and shear
Abstract : A great number of society's resources are invested in existing concrete structures, such as bridges, tunnels, different kind of buildings etc. All of these structures have both an expected function and an expected life span. However, both the function and the life span can be influenced by external factors, e.g. READ MORE
