| dc.description.abstract | This master thesis will be based on a real-world project where the author’s employer – Projekt Planung AS were responsible for the structural engineering. The building is the Kristinakvartalet / Kristina Quarter in Tønsberg, an angled, partially rectangular concrete structure which will be expanded by three stories in height. In addition, there will be modifications of certain structural parts to streamline the projects workflow and reduce costs.
With the expansion of three additional stories, the building have increased load and dynamic properties, and will require to be analysed for both static and new dynamic characteristics, if not assessed for omission criterias in regard to seismic dimensioning.
This thesis will focus on analysing the structure before and after expansion for dynamic properties, both with various materials used in the expanded stories, using FEM software and hand calculations based on the proceedings described in the Eurocode standard. Further, these results will be used to evaluate the structure, as well as the process and difficulties around the omission criterias with its strengths and weaknesses.
During the process for the thesis, I have learned a tremendous amount about how an analysis is performed with all the steps and data, but also much of the theory behind it. This comes from both the standards, guidelines and the academic theory found in scientific journals that have been used in the thesis. This process have truly made me very interested in working with seismic analysis of structures in the future.
I would like to thank my supervisors during the analysis and writing of this thesis – my colleague Jacob C Emesum, M.Sc at Projekt Planung, and Associate Professor Mahdi Kioumarsi, P.hD at Oslo Metropolitan University. | en_US |
