  1. 1. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

    Master-uppsats, KTH/Betongbyggnad

    Författare :David Andersson; [2022]
    Nyckelord :Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

    Sammanfattning : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.

  3. 2. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Författare :Henrik Johansson; Martin Heinegård; [2020]
    Nyckelord :Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Sammanfattning : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. LÄS MER

  4. 3. Dimensionering av höga balkar av armerad betong : En jämförelse mellan EK2, BBK, laboratorieförsök och ATENA 2D

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

    Författare :Evelina Karlsson; [2020]
    Nyckelord :Deep beams; nonlinear analysis; Strut and tie model; ATENA; Eurocode 2; Calculation model; BBK 04; Höga Balkar; Ickelinjär analys; Fackverksanalys; ATENA; Eurokod 2; Beräkningsmodell; BBK 04;

    Sammanfattning : Detta examensarbete vid Luleå tekniska universitet har utförts i samarbete med avdelningen för byggkonstruktionvid det nordiska konsultföretaget Norconsult AB. Arbetet bygger på en önskan från Norconsultatt ta fram en beräkningsmodell för höga balkar i överensstämmelse med Eurokod 2 motsvarande densom finns i BBK 04. LÄS MER

  5. 4. Safety formats for non-linear finite element analyses of reinforced concrete beams loaded to shear failure

    Master-uppsats, KTH/Betongbyggnad

    Författare :Anton Ekesiöö; Andreas Ekhamre; [2018]
    Nyckelord :nonlinear finite element analysis; estimation of coefficient of variation; par- tial factor; model uncertainty; deep beams; shear;

    Sammanfattning : There exists several different methods that can be used to implement a level of safety when performing non-linear finite element analysis of a structure. These methods are called safety formats and they estimate safety by different means and formulas which are partly discussed further in this thesis. LÄS MER

  7. 5. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground

    Master-uppsats, KTH/Betongbyggnad

    Författare :Shruthi Prakash; [2018]
    Nyckelord :Slabs-on-ground; Gradient shrinkage; Statical indeterminate structure; Vertical deflection and Cracking;

    Sammanfattning : Concrete slabs-on-ground are commonly used in many types of industrial floors, warehouses, highways, parking lots and buildings. Cracks and deflection of slabs are undesired events caused by differential shrinkage, which limits the service life of the slabs. LÄS MER
