  1. 1. 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

  3. 2. Formrivningsprognostisering med HETT22 : En jämförelsestudie av HETT 22 som prognosverktyg

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Emil Karlsson; Kristoffer Löfving; [2023]
    Nyckelord :Prognostic tool; compressive strength; temperature development; simulation; form removal; winter casting; HETT 22; prognosverktyg; tryckhållfasthetsutveckling; temperaturutveckling; simulering; formrivning; vintergjutning;

    Sammanfattning : The increase of population results in more housing buildings and infrastructure, which increases the need for stable concrete structures that can safely accommodate people. In countries like Sweden, where temperatures are below zero for several months a year, housing construction cannot come to a halt. LÄS MER

    Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

  5. 4. Jämförelse mellan platsgjutna väggar och håldäckselement kontra stålstomme och plattbärlag

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Mayar Khalaf; Amjad Al-Rebdawy; [2023]
    Nyckelord :;

    Sammanfattning : Environmental issues are becoming increasingly relevant, and the construction sector faces a dilemma when it comes to making building projects more environmentally friendly without exceeding costs and time frames. Three major aspects, environmental impact, costs and the time period are interconnected and influence each other based on the choice of materials used in the design. LÄS MER

  7. 5. Dynamisk analys av betonghåldäck : Parametrisk FEM studie

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Angelica Drakneid; Jasmine Weber; [2023]
    Nyckelord :;

    Sammanfattning : Hollow-core concrete slabs can be used in buildings to achieve longer floor spans in comparison to regular concrete slabs. However, longer floor spans in combination with low dead-weight make them more susceptible to vibrations.Frequencies between 0-15 Hz are relevant to study since these lower frequencies affect the comfort of humans.
