  1. 1. Jämförelse mellan grundläggningsmetoder för lera med begränsat djup

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Isak Ekström; Taulant Lutfiu; [2023]
    Nyckelord :Short piles; land excavation; environment; soil replacement; Grundläggningsmetoder; kostnad; korta pålar; miljö; utskiftning;

    Sammanfattning : This thesis compares foundation methods for buildings on low-strength, limited-depth soil. The study focuses on soil replacement and piling, specifically concrete and steel piles. The studyaims to answer the key questions about the possibility to use short piles on limited depth, cost-efficiency, and environmental impact of these methods. LÄS MER

  3. 2. Buckling of Short End-Bearing Piles in Clay

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :David Ebenhardt; Jonas Stener; [2022]
    Nyckelord :Short piles; buckling; elastic buckling length; initial deflection; finite element method; Eurocode 3;

    Sammanfattning : Structural design of piles with respect to buckling in Sweden is commonlymade in accordance with the calculation model from the Commission ofPile Research, PKR. A prerequisite for this model is that the elasticbuckling length of the pile is shorter than the physical length. LÄS MER

  4. 3. Lagring av skogsflis med och utan täckning : substansförlusters påverkan av nederbörd och vind

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Daniel Wetterholm; [2021]
    Nyckelord :biobränsle; bränslekvalitet; substansförluster; fukthalt; data analys; lagring;

    Sammanfattning : In the supply chain for wood chips, storage is a neccesary part due to seasonal demand. During storage there are several mechanisms occuring, cell respiration, biological degradation and thermo-chemical oxidative reaction. All of the mentioned mechanisms lead to increased temperature, loss of dry matter and energy. LÄS MER

  5. 4. Optimization and automatization of end-bearing pile groups

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Gabriel Antonio Del Pozo Alarcon; [2021]
    Nyckelord :Optimization; automatization; pile groups; Optimering; automatisering; pålgrupper;

    Sammanfattning : This thesis consists of the development, trial an application of a computational tool that by the use of the Genetic Algorithm optimization method provides the user with an alternative approach from the traditional trial and error when faced with the challenge of designing end bearing pile groups.The work presents the three main concepts needed for understanding the computational tool as well as the structure of it.

  7. 5. 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
