Sammendrag
This thesis looks at the self-raising roof built on a bullring in X`ativa [1] and tries toapply the same construction method and procedure used, on a different structure, underNorwegian conditions. A new structure is designed, with some similarities to the X`ativaroof. Multiple analyses of the new structure are done, as to assure that the design canwithstand the different positions. SAP2000 is the software used to do the analyses,which encompasses examining the element forces in the truss structure and running asteel capacity check for the structure. Using these results a steel design is proposed.The method that allows the structure to self-raise is a version of the Pantadome Systemthat applies a clever use of post-tension jacks. The forces that the jacks need to produceis found for the new structure. As the new roof is in a vulnerable position while lifting,a high safety factor is used, which the design passed. Design of details thought to becritical are suggested and drawings of the final design are presented.
