  1. 6. Global Analysis and design of a complex slanted High-Rise Building with Tube Mega Frame

    Master-uppsats, KTH/Betongbyggnad

    Författare :Hamzah Al-Nassrawi; Grigorios Tsamis; [2017]
    Nyckelord :Tubed Mega Frame; Tall Buildings; Inclined structures; Structural Analysis; ETABs.; Tubed Mega Frame; Höga byggnader; Lutande strukturer; Strukturell analys; ETABS;

    Sammanfattning : The need for tall buildings will increase in the future and new building techniques will emerge to full fill that need. Tyrénshas developed a new structural system called Tube Mega Frame where the major loads are transferred to the ground through big columns located in the perimeter of the building. LÄS MER

  3. 7. Earthquake Analysis Using a Migration Based Detection Algorithm Applied to Local Earthquake Data

    Kandidat-uppsats, Uppsala universitet/Geofysik

    Författare :Stefan Johansson; [2017]
    Nyckelord :migration; stacking; earthquake detection; migration; stacking; detektering av jordskalv;

    Sammanfattning : In this study earthquake data is analyzed using a newly developed Migration Based Detection (MBD) algorithm (Wagner et al. 2017). LÄS MER

  4. 8. Effect of Petrophysical Parameters on Seismic Waveform Signatures : Review of Theory with Case Study from Frigg Delta Oil Field, Norway

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Gardar Gislason; [2016]
    Nyckelord :AVO; poroelasticity; AVFO; WIFF; seismic attenuation; seismic dispersion; AVO; poroelasticitet; AVFO; WIFF; seismisk dampning; seismisk dispersion;

    Sammanfattning : Conventional AVO analysis has been used for the past 4 decades to aid in locating oil and gas reservoirs for extraction. It is, however, not possible to use it to acquire information on the porosity of the rock, the fluid saturation or other important petrophysical parameters. LÄS MER

  5. 9. Behavior of Swedish Concrete Buttress Dams at Sesmic Loading

    Master-uppsats, KTH/Betongbyggnad

    Författare :Erik Forsgren; Isak Berneheim; [2016]
    Nyckelord :seismic; Swedish earthquake; buttress dam; concrete; finite element analysis; seismik; jordbävning; lamelldamm; betong; finit element analys;

    Sammanfattning : The aim of the thesis is to study the response of Swedish buttress dams if they are subjected to an earthquake of relevant magnitude to Sweden. Swedish dams are evaluated for an extensive amount of load cases, but not for earthquake loading. Therefore, it is not known how the Swedish buttress dams would respond during such loading. LÄS MER

  7. 10. Cost Evaluation of Seismic Load Resistant Structures Based on the Ductility Classes in Eurocode 8

    Master-uppsats, KTH/Betongbyggnad

    Författare :Georgios Valdemar Drivas; [2014]
    Nyckelord :Seismic Design; Eurocode 8; Norwegian Annex; Ductility class low; Ductility class medium; Economical Assessment; Precast Structures; Jordbävningsdimensionering; Eurokod 8; Norskt annex; Duktilitetsklass låg; Duktilitetsklass medium; Lönsamhetsbedömning; Prefabricerade konstruktioner;

    Sammanfattning : Most people do not associate Scandinavia with seismic activity and earthquakes; however, there is in fact seismic activity in the region. Although in comparison with southern Europe the return periods of earthquakes with large magnitudes are quite long, itis critical to consider earthquake impact when designing structures. LÄS MER
