  1. 1. Structural Earthquake Response Analysis

    Detta är en avhandling från Chalmers University of Technology

    Författare :Hamid Movaffaghi; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; Earthquake excitation; structural earthquake response analysis; finite element method; global and local optimization; viscoelastic passive dampers; stochastic simulation;

    Sammanfattning : Abstract Earthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. LÄS MER

  2. 2. Earthquake Sources and Hazard in northern Central America

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Diego José Cáceres Calix; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Northern Central America; Probabilistic Seismic Hazard; Body waveform modeling; Seismic Active Deformation; Earthquake Triggering; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Sammanfattning : Northern Central America is a tectonically complex zone defined by its borders with Cocos and North America plates. The Middle America subduction zone and the strike-slip motion along the North America-Caribbean plate boundary, in that order, control most of its deformation. LÄS MER

  3. 3. Analysis of underground concrete pipelines subjected to seismic high-frequency loads

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Roghayeh Abbasiverki; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Earthquake; High-frequency; Underground; Pipelines; Reinforced concrete; Inclined bedrock; Jordbävning; Högfrekvent; Underjordisk; Rörledningar pipelines ; Armerad betong; Lutande berggrund; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.

  4. 4. Seismic high-frequency content loads on structures and components within nuclear facilities

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Cecilia Rydell; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear power plant; Earthquake; Seismic high frequencies; Fluid-structure interaction; Piping; Concrete; Pool;

    Sammanfattning : Sweden is generally considered to be a low seismicity area, but for structures within nuclear power facilities, the safety level demand with respect to seismic events are high and thus, these structures are required to be earthquake-resistant. The seismic hazard is here primarily considered to be associated with near-field earthquakes. LÄS MER

  5. 5. Human Adaptation to Danger

    Detta är en avhandling från Swedish National Defence College, Järnvägsgatan 6, SE-652 25 Karlstad

    Författare :Claes Wallenius; Försvarshögskolan.; Lunds universitet.; Lund University.; [2001]
