  1. 1. A place in between places

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ana Gilmet Lejtreger; [2023]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Skellefteå is calibrating its position in multiple overlapping maps, sometimes located in the centre and sometimes in the periphery (if those are even relevant). It is a place in between places. A geographical periphery of Europe that becomes one of the centres of production of one of the fastest growing industries in the world. LÄS MER

  3. 2. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Sicong Wei; [2020]
    Nyckelord :high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

    Sammanfattning : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. LÄS MER

  4. 3. Betongkvalitetens inverkan på byggtid och kostnader vid anläggningsprojekt

    M1-uppsats, KTH/Byggteknik och design

    Författare :Elsa Tesfamichael; Laxmi Roka; [2018]
    Nyckelord :;

    Sammanfattning : In the pursuit to complete a construction project in a shorter period of time, a number of studies have been published and methods tested. This thesis study examines if it is profitable to use a higher quality concrete than constructional needed to gain time and economical savings in the production phase of a construction project.

  5. 4. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Turgay Dagdelen; Shaho Ruhani; [2018]
    Nyckelord :Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Sammanfattning : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  7. 5. Utbyte av rullager i höghållfast stål : En jämförande studie av metod och problematik

    M1-uppsats, KTH/Byggteknik och design

    Författare :Isak Selder; Salim Aly; [2018]
    Nyckelord :rullager; brolager; höghållfast stål; utmattning; korossion; utbyte; säkerhespallning;

    Sammanfattning : Different kinds of bridges require different kinds of bearings. The Swedish Traffic Agency (Trafikverket) maintains 53 bridges in Sweden with high strength steel roller bearings. These kinds of bearings may cause failure due to fatigue and corrosion and therefore they need to be replaced as a safety reason. LÄS MER
