11. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

12. Framtagning av en Vakuumisolerad kryotank
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : I dagens samhälle är flygplan det snabbaste och ibland ett livsviktigt transportmedel. Med nutidens teknologi är det inte möjligt att tillverka ett passagerarflygplan som drivs av el då det skulle bli för tungt. Elen produceras av bränsleceller som drivs av vätgas. LÄS MER
13. Optimization of structures byincluding modeling of pilefoundations : A parametric study on using stiff supports orpiles in a model
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : Structural engineers use rules and regulations in the form of Eurocodes and other supplementary guidelines to design different type of structures. However, the uncertainty surrounding each case and the actual outcome that depends on decisions made throughout the design phase are of most importance and must be handled properly from start.

14. Global buckling of subsea pipelines with DEH cable
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. LÄS MER
15. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes
Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)Sammanfattning : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. LÄS MER
