  1. 21. Dynamic analysis of the Baozhusi dam using FEM.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Zaid Alsuleimanagha; Jing Liang; [2012]
    Nyckelord :Baozhusi dam; Wenchuan earthquake; Finite element method; ABAQUS; Time history method;

    Sammanfattning : High magnitude earthquakes have devastating effects that leads to severe human and material losses; when affecting concrete gravity dams, seisms devastate the surrounding habitat through sudden release of reservoir. Dam safety is therefore a significant issue to be accounted in order to prevent the failure of dams located in seismic regions. LÄS MER

  3. 22. Influence of In-filledTrench as Wave Barrier on Ground Vibrations

    Uppsats för yrkesexamina på avancerad nivå, KTH/Jord- och bergmekanik

    Författare :Leilei Xu; [2012]
    Nyckelord :ground vibration; cell foam; velocity amplitude; particle velocity;

    Sammanfattning : With the development and expansion of traffic systems, problems associated with ground vibrations have required increased attention. Increasing vehicle loads,traffic volumes, and aging roads and railways,vibrations induced by traffic are gradually becoming acrucialproblem. LÄS MER

  4. 23. Earthquake Analysis of Pipe Supports in Nuclear Power Plants

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Johan Mattsson; [2012]
    Nyckelord :structural analysis; earthquake engineering; mechanics; time history; spectrum; Abaqus; Pipestress; nuclear plant; pipe support; Technology and Engineering;

    Sammanfattning : This is the resulting rapport from a master thesis in the field of structural analysis, with a focus on earthquake engineering. In this project are pipe supports’ impacts on seismic design analysed. This is done by modelling a building, pipe supports and a pipe system in two different computer softwares. LÄS MER

  5. 24. Seismic performance of a  bridge subjected to far-field  ground motions by a Mw 9.0  earthquake and near-field  ground motions by a Mw 6.9  earthquake

    Uppsats för yrkesexamina på avancerad nivå, KTH/Bro- och stålbyggnad

    Författare :Reina Goto; [2012]
    Nyckelord :seismic performance; dynamic response analysis; far-field ground motions; near-field ground motions;

    Sammanfattning : In the last two decades, two major earthquakes have occurred in Japan: the 1995 Kobe earthquake and the 2011 Great East Japan earthquake. In the 2011 Great East Japan earthquake, many bridge structures were destroyed by the tsunamis, but it is interesting to study the ground motion induced damage and also how this earthquake differed from the one in 1995.

  7. 25. Re-processing and Interpretation of 2D Seismic Line in the Kristineberg Mining Area, Northern Sweden

    Master-uppsats, Geofysik

    Författare :Siddique Akhtar Ehsan; [2011]
    Nyckelord :;

    Sammanfattning : The Skellefte district, 1.90 to 1.80 Ga, is one of the most important base metal mining districts of Sweden with over 85 volcanic-hosted massive sulfide (VHMS) deposits. The study area focuses on the western part of the Skellefte district which contains volcanic, metasedimentary and intrusive rocks. LÄS MER
