  1. 1. From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jonatan Gripenberth; [2023]
    Nyckelord :Topologioptimiering; Implicita kroppar; Arbetsflöde; Icke-linjär finita element analys;

    Sammanfattning : A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. LÄS MER

  3. 2. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    Master-uppsats, KTH/Betongbyggnad

    Författare :Mohammad Mustafa Angar; [2020]
    Nyckelord :Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Sammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER

  4. 3. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Simon Stahlin; [2019]
    Nyckelord :composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Sammanfattning : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. LÄS MER

  5. 4. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Turgay Dagdelen; Shaho Ruhani; [2018]
    Nyckelord :Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Sammanfattning : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  7. 5. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

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

    Författare :Andreas Ekman; Christoffer Sandin; [2018]
    Nyckelord :Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Sammanfattning : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. LÄS MER
