21. Soil-structure interaction of end-frames for high-speed railway bridges
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : In this thesis, the influence of soil-structure interaction (SSI) of end-frame bridges for high-speed railways was studied. Impedance functions, representing the SSI, was calculated and analyzed. The impedance functions were applied to end-frame bridge models which were analyzed for use in HSR. LÄS MER
22. Analysis of Jointless Bridges due to Horizontal Actions and Soil-Structure Interaction
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för KonstruktionsteknikSammanfattning : Bridges constructed without joints function to take care of forces by introducing bending moments to the stiff connections. Jointless bridges, also called integral bridges, in different appearances are built all over the world, and are popular due to their advantages regarding life cycle cost. LÄS MER
23. Development of a Parallel Finite-element Tool for Dynamic Soil-structure Interaction : A Preliminary Case Study on the Dynamic Stiffness of a Vertical Pile
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : This thesis has two major goals; first to develop scalable scripts for steady-state analysis, then to perform a case study on the dynamic properties of a vertical pile. The scripts are based on the numerical library PETSc for parallel linear algebra. This opens up the opportunity to use the scripts to solve large-scale models on supercomputers. LÄS MER
24. FEM Modelling of Piled Raft Foundations in Two and Three Dimensions
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/GeoteknikSammanfattning : In conventional design of pile foundations, all loads are taken by the piles, i.e. the contact pressure between the raft and the soil is neglected. In the last decades geotechnical engineers have started to take this pressure into account in design of pile foundation. LÄS MER
25. Dynamic analysis of a portal frame railway bridge using frequency dependent soil structure interaction
Uppsats för yrkesexamina på avancerad nivå, KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVGSammanfattning : With the development of high-speed railroads the dynamic behaviour of railroad bridges is increasingly important to explore. Deeper knowledge about the influence of different factors and what should be included in a model is essential if the designer shall be able to make reliable estimates of responses in existing and new structures.
