  1. 1. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Musole Kambita; [2022]
    Nyckelord :Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Sammanfattning : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. LÄS MER

  2. 2. An investigation of the design of cylinderical steel tanks modelled according to EN14015 and according to the Eurocodes

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Yonas Gebre; [2022]
    Nyckelord :Keywords: Steel tank; Wind; Snow; FEM; Shell buckling; Non-linear analysis;

    Sammanfattning : Abstract Storage tanks are above or below ground vessels for storing chemicals, petroleum and other liquid products. Above ground vertical cylindrical shells are typically thin walled structures prone to buckling and lose their stability especially when they are empty or have lower fluid level due to external loads.

  3. 3. Numerical and experimental study of light-frame shear walls

    Magister-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Rajan Maharjan; Mohamad El Rachid; [2019]
    Nyckelord :wood; shear wall; FEM analysis; ABAQUS; experiment; stiffness; racking deformation;

    Sammanfattning : In recent time, some of the construction processes of multi-storey timber buildings are achieved by using prefabricated volume modules since this method is very beneficial due to its high prefabrication level and the fast on-site assembly of the modules. The main structural component of these modules is a light-frame shear wall that stabilizes these modules from the effect of horizontal forces. LÄS MER

  4. 4. Tank Shell Design According to Eurocodes and Evaluation of Calculation Methods

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Malin Pluto; [2018]
    Nyckelord :Tank; Eurocode; Membrane theory; Linear elastic shell analysis; Finite element method;

    Sammanfattning : Tanks are storage vessels for liquids. They can have different appearances; some are short and wide, others are tall and slim, some are small, others are large. In this thesis a tank of 6 m in both diameter and height has been used to obtain numerical results of the stresses in the tank. LÄS MER

  5. 5. FE modeling of bolted joints in structures

    Master-uppsats, Hållfasthetslära; Tekniska högskolan

    Författare :Alexandra Korolija; [2012]
    Nyckelord :Bolted joints; Fastener joints; Load distribution; Flexibility; Connector element;

    Sammanfattning : This paper presents the development of a finite element method for modeling fastener joints in aircraft structures. By using connector element in commercial software Abaqus, the finite element method can handle multi-bolt joints and secondary bending. The plates in the joints are modeled with shell elements or solid elements. LÄS MER
