  1. 1. Investigation of methods to analyse global stability of a reinforced concrete stabilising core

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Evelina Husak; Ellinor Persson; [2022]
    Nyckelord :;

    Sammanfattning : Ensuring the structural stability of a building is an evident requirement for the building to be safe to use. This becomes a qualified task for a structural engineer. Ensuring stability has become especially important nowadays while stabilising elements often are kept to a minimum and tall buildings are common. LÄS MER

  3. 2. Stability of building structures using NLFEA including second order effects : Applications with the software ATENA-GiD

    Master-uppsats, KTH/Betongbyggnad

    Författare :Alexandros Petkoglou; [2021]
    Nyckelord :Non-linear analysis; second order effects; prefabricated buildings; ATENA; GiD; slip connection; Icke-linjär analys; andra ordnings effekter; förtillverkade byggnader; prefabricerade byggnader; ATENA; GiD; glidkoppling;

    Sammanfattning : In Sweden, prefabrication in the construction industry is a very common system. In prefabricated structures, there are various kinds of connections and generally many hinged connections. Therefore, it is of high interest to study the behavior of the prefabricated buildings in relation to the connections. LÄS MER

  4. 3. Stability analysis and modelling of a structure with corrugated roof

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Nikola Tosovic; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Corrugated galvanized iron (CGI), or corrugated sheet metal, is a lightweight roofing material that was invented in the early 1800s. The corrugation gives the steel an increased flexural strength in its installed direction and thus increases the amount of load the CGI-plate is able to carry and the span it can be effective at.

  5. 4. Jämförande beräkningar av betongpelare

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Caroline Rosenqvist; [2018]
    Nyckelord :Betongpelare; armeringsmängd; andra ordningens teori; slankhet; nominella styvhetsmetoden.; Technology and Engineering;

    Sammanfattning : När en betongpelare dimensioneras ska dess kritiska tvärsnitt bestämmas och dimensioneras med hänsyn tagen till pelarens slankhet och andra ordningens effekter. Dessa parametrar kan begränsa pelarens bärförmåga och riskera knäckning istället för att tvärsnittets kapacitet blir avgörande. LÄS MER

  7. 5. Design of Glulam Columns According to Eurocode 5 - Influence of Various Parameters and Methods of Analysis

    Kandidat-uppsats, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Författare :Emil Nilsson; [2018]
    Nyckelord :Glulam; Eurocode 5; Finite element method; First order theory; Second order theory; Structural analysis; Technology and Engineering;

    Sammanfattning : More and more structural analyses today are being conducted with computer-based tools in comparison to traditional methods using hand calculations. The development, according to the Norweigan scientist Kolbein Bell is shifting from using first order analyses with correction factors, to using second order analyses, with computer-based tools.
