  1. 6. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    University essay from KTH/Betongbyggnad

    Author : Viktor Peterson; Zihao Wang; [2020]
    Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2-method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings; Olinjär tids-historikanalys; olinjär stjälpningsanalys; N2-metoden; ekvivalent rammodell; kontinuumelement modell; numerisk jordbävningsanalys; oarmerade murverksbyggnader;

    Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be found in Groningen, the Netherlands. More and more induced earthquakes with short duration have been detected in this region due to gas exploitation. READ MORE

  3. 7. Seismic analysis and retrofitting of an existing multi-storey building in Stockholm

    University essay from KTH/Betongbyggnad

    Author : Matilda Muca; Celine Haikal; [2018]
    Keywords : Earthquakes; seismic analysis; retrofitting; frequency; multi-storey building; shear wall; steel bracing; Jordbävningar; seismisk analys; förbättring av skadade byggnader; flervånings-byggnad; skjuvvägg; stålfackverk;

    Abstract : Throughout the years earthquakes are a huge concern for structures; causing losses of peoples’ lives, damages and collapse of homes. Usually, most of the buildings that collapse or have serious damages are mostly old buildings that do not fulfil any longer the updated regulations and building codes concerning seismic design.

  4. 8. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jennifer Eriksson; [2018]
    Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

    Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE

  5. 9. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Jonsdottir; [2018]
    Keywords : Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Abstract : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. READ MORE

  6. 10. Blockchain Based Electronic Health Record Management For Mass Crisis Scenarios : A Feasibility Study

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Filippo Boiani; [2018]
    Keywords : ;

    Abstract : Electronic Health Records (EHRs) are both crucial and sensitive as they contain essential information and are frequently shared among different parties including hospitals, pharmacies or private clinics. This information must remain correct, up to date, private, and accessible only to the authorized people. READ MORE
