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

    University essay from KTH/Bro- och stålbyggnad

    Author : Evelina Husak; Ellinor Persson; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Westlund; [2019]
    Keywords : bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Abstract : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. READ MORE

  4. 3. Prediction of paperboard thickness and bending stiffness based on process data

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Sacha Vandenbossche; [2019]
    Keywords : ;

    Abstract : Bending stiness is one of the most important mechanical properties in paperboard making,giving rigidity to panels and boxes. This property is currently only possible to measure bydestructive measure o the production line. READ MORE

  5. 4. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mattheüs Lucassen; [2019]
    Keywords : Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Abstract : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. READ MORE

  6. 5. Second-order FE Analysis of Axial Loaded Concrete Members According to Eurocode 2

    University essay from KTH/Betongbyggnad

    Author : Nessa Yosef Nezhad Arya; [2015]
    Keywords : Second-order; nonlinear; slender reinforced concrete column; ABAQUS; FE analysis; curvature method; nominal stiffness method; eccentrically loaded; benchmark experiment; parametric study; Andra ordningens effekt; icke-linjär; slank armerad betongpelare; ABAQUS; FE-modellering; krökningsmetoden; styvhetsmetoden; excentrisk last; utvärderingsförsök; parameterstudie;

    Abstract : A nonlinear finite element analysis was performed for an axial loaded reinforced concrete column subjected to biaxial bending taking into account second-order effects. According to Eurocode there are two ways to take second-order effects into consideration: nonlinear FE analysis and hand calculation based on the simplified methods explained in Eurocode 2. READ MORE
