2. Vibration reduction over junctions in buildings
University essay from KTH/Marcus Wallenberg Laboratoriet MWLAbstract : Structure borne sound can travel multiple paths from one office to another and choosing to sound insulate a specific building element can be difficult since all the building elements are connected together and form a coupled system. The current approach by engineers when investigating transmission paths between spaces in a building is using a computer model and assuming that the junctions are firmly clamped or free. READ MORE

4. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats
University essay from Luleå tekniska universitet/Byggkonstruktion och -produktionAbstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE
