6. On the dynamics of footbridges : A theoretical approach and a comparison between running and walking loads
Abstract : 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. READ MORE

7. Optimal design solutions of road bridges considering embedded environmental impact and cost
Abstract : Continuous urbanization and population growth are increasing the demand for transportation infrastructure such as bridges. The construction of these structures represents a significant economic investment for public authorities; moreover, the construction sector accounts for a big portion of CO2 emissions. READ MORE

8. Dynamic soil-structure interaction of simply supported high-speed railway bridges
Abstract : Research performed on the subject of dynamic soil-structure interaction (SS) concerning railway bridges is presented in this thesis with the focus on simply supported railway bridges supported by shallow foundations in soil strata on bedrock. The research aims to obtain insight into the SSI of high-speed railway bridges and to provide recommendations on how to model the soil-bridge system from a design perspective. READ MORE

9. Experimental and Numerical Analyses of the Dynamic Behaviour of Hollow-Core Concrete Floors
Abstract : Precast hollow-core (HC) concrete slabs are widely used in construction, especially in Nordic countries. The combination of prestressing and low self-weight due to the voids makes it possible to build long-span floors. However, this also implies that the HC concrete floors become more sensitive to vibrations from human activities. READ MORE

10. Towards a sustainable road infrastructure in an age of digitization: opportunities and challenges
Abstract : Pavement system plays an indispensable role in the socio-economic and sustainable development of every modern society. Yet, pavement construction and maintenance is also responsible for a significant fraction of the GHG emissions from the whole transport sector. READ MORE
