  1. 16. Second-order FE Analysis of Axial Loaded Concrete Members According to Eurocode 2

    Master-uppsats, KTH/Betongbyggnad

    Författare :Nessa Yosef Nezhad Arya; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Dual-Probe Shear Wave Elastography in a Transversely Isotropic Phantom

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Gioia Bassan; [2015]
    Nyckelord :Shear Wave Elastography; Transversely isotropic phantom;

    Sammanfattning : Shear Wave Elastography (SWE) is an ultrasound based technique which is able to measure tissue stiffness through the speed of induced shear waves. Tissue stiffness is often related to pathological conditions and detecting mechanical changes can help the recognition of potential diseases. LÄS MER

  4. 18. Dimensionering av en bågbro i trä - jämförelse av handberäkningar och Finita Element Metoden

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Jimmy Tran; Anh Tuan Tran; [2012]
    Nyckelord :Arch bridge; timber bridge; stress laminated timber deck; FEM; hand calculation; plate model; shell element; frame element solid element.; Technology and Engineering;

    Sammanfattning : In the past it was common to build in timber but in the last 150 years, steel and concrete in particular have been the dominating material in bridge-buildings. This is mainly due to not having mastered the timber construction to the same extent as steel and concrete. LÄS MER

  5. 19. Structural strength of work boatsand high speed crafts with floatingframes

    Master-uppsats, KTH/Marina system

    Författare :Jon Englund; [2009]
    Nyckelord :;

    Sammanfattning : This thesis investigates the usage of floating frames in boats. A floating frame is a transverse frame fittedto the longitudinal stiffener flanges without contact with the shell plating, as opposed to the traditionalfixed frame which is welded to the shell plating with the stiffeners most commonly fitted through cut outsin the frame.

  7. 20. Simulation of Solutions to Excessive Vibration Problems of Pedestrian Footbridges

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Ezeonwu-Emmanuel Chinedu; Ukoha-Christian Oji; [2008]
    Nyckelord :Dampimg; Modelling; Footbridges; Resonance; ABAQUS; MATLAB.;

    Sammanfattning : Footbriges are often prone to vibrations induced by pedestrian loading. They are long and slender and their weight is moderate. One of the classical and famous examples is the transverse vibrations encountered on the millennium bridge in London. LÄS MER
