  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. Hybrid bridge deck of timber and corrugated steel plates

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Muze Lu; [2023]
    Nyckelord :;

    Sammanfattning : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. LÄS MER

  4. 3. Harmonised traffic load model between Eurocode 1 - part 2 (EN 1991-2) and TRV specifications : A pilot study on reinforced concrete portal frame bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
    Nyckelord :;

    Sammanfattning : The advancement of society has led to an increase in demand for infrastructure, particularly bridges, which are designed in accordance with different design codes. In Sweden, bridge design adheres to the Eurocode and national code (TRV specifications), with the most adverse scenario of the two codes determining the basis for bridge design. LÄS MER

  5. 4. Växa mot Våtmarken

    Uppsats för yrkesexamina på grundnivå, KTH/Arkitektur

    Författare :Klara Bakhuizen; [2023]
    Nyckelord :Nynäshamn; wetland; rammed earth; exhibition;

    Sammanfattning : Projekt "Växa mot Våtmarken" handlar om att skapa en byggnad som tar människan till naturen, och inte minst våtmarken. Nynäsvägen och järnvägen till Norviks hamn skapar idag barriärer för Nynäshamnsborna att ta sig till Alhagens våtmark, ett vackert naturområde med stora värden för naturen och människan. LÄS MER

  7. 5. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Nyckelord :high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Sammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER
