  1. 11. Spectral density approach for dynamic analysis of high-speed railway bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Alket Ciku; Vlad Gavriliuc; [2022]
    Nyckelord :;

    Sammanfattning : The focus of this thesis is to introduce the concept of train signature in the spectraldensity approach used in the dynamic analysis of simply-supported railway bridges.Due to the increased transportation demands, longer trains with higher axles loadsand top speeds are being developed.

  3. 12. Development of a model-free damage detection algorithm using AR-models and its application to a riveted steel railway bridge

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Mattis Johannes Frenz; [2022]
    Nyckelord :;

    Sammanfattning : Bridges are one of the most important structures in our infrastructural system today.The modern society depends on these structures which in majority are nearingthe end of their design life. Therefore, the need for monitoring of bridges is increasing. LÄS MER

  4. 13. Explorativ graffiti. Flerdimensionalitet och polyagenter

    Master-uppsats,

    Författare :Willie Nordström; [2021-02-26]
    Nyckelord :Graffitiarkeologi; Kulturarv; Polyagens; Mikroarkeologi; Strukturalism; Samtidsarkeologi; digitalt frottage; Vallda; Lerkil; Hol; Tumberg; Bälinge; Alingsås; Kungsbacka; Vårgårda;

    Sammanfattning : Graffiti is a widespread term, often referring to illicit or troublesome imagery practices. In this essay graffiti from four independent locales has been explored through a polyagentive multidimensional approach. How changes in attitudes and uses, as well as agents affects and effects on one another beyond time will be central for these analysis´. LÄS MER

  5. 14. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Rasmus Elm Dahlman; Emil Lundberg; [2021]
    Nyckelord :Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

    Sammanfattning : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. LÄS MER
