  1. 1. Production Process for Tunnel Modeling : An Analysis of Composites for Water Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Melody Ghaderidosst; Vilma Hurtigh Grabe; Rebecka Norman; Adam Rosvall; Evelina Wiksten; [2021]
    Keywords : Tunnel Modeling; Water Applications; Composites; Natural Fibers; Polymers;

    Abstract : Hydroelectric power is a leading source of renewable energy where large turbines convert the kinetic energy of water into electricity. In order to not exceed the capacity limit of the turbine, excess water in the dams needs to be diverted away through spillways. READ MORE

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

    University essay from KTH/Betongbyggnad

    Author : Alexandros Petkoglou; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 3. Shear stiffness of cross laminated timber diaphragms - A study of the influence of connection and member stiffness

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Gustaf Olausson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Since ancient times, buildings have been constructed with the use of timber and during the modern era, new types of timber products have been developed. Today, more constructions, especially residential buildings are being built with timber as the main load-bearing material. READ MORE

  5. 4. Influence of structural and materials properties on the flexural strength of laminated high-density cellulose fiberboards

    University essay from KTH/Hållfasthetslära

    Author : Ola Serck; [2021]
    Keywords : ;

    Abstract : Laminated pressboard is a structural electrical insulation material used in power transformers. Typical applications are areas in the power transformers where high mechanical forces are present such as pressrings or winding tables and cleats which support the electrical cables connecting the transformer windings to tap-changes and bushings.

  6. 5. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    University essay from KTH/Jord- och bergmekanik

    Author : Maya Sleiman; [2021]
    Keywords : ;

    Abstract : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.
