1. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER
2. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

3. Spectral density approach for dynamic analysis of high-speed railway bridges
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The focus of this thesis is to introduce the concept of train signature in the spectraldensity approach used in the dynamic analysis of simply-supported railway bridges.Due to the increased transportation demands, longer trains with higher axles loadsand top speeds are being developed.

4. Dynamic Analysis of Double Tee Floors Subjected to Human Activity : A comparison between a standard- and a modified cross section
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : Building with larger spans and more slender elements is more common today since the demand for open floor plans has increased. The consequence is that low frequency floors and vibration problems arise. Such floors tend to undergo large vibrations since their low eigenfrequency coincides with the frequency which human activities have. LÄS MER
5. Phase Diagrams of Finite Spin Chains with Coupled Spin and Lattice Vibrations
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : The spin-lattice coupling is due to itinerant electrons interacting with both spins of ions and phonons, mediating a coupling between magnetic spin moments and lattice vibrations. In this project, the coupling is studied systematically for finite quantum spin chains of size 2 – 10. LÄS MER
