1. 16. Empirical correlation between undrained shear strength and preconsolidation pressure in Swedish soft clays

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Erik Persson; [2017]
   Nyckelord :undrained shear strength; preconsolidation pressure; empirical correlations; fall cone test; direct simple shear test; correction factor; soft clay; odränerad skjuvhållfasthet; förkonsolideringstryck; empiriska korrelationer; fallkonförsök; direkta skjuvförsök; korrektionsfaktor; lera;

   Sammanfattning : The undrained shear strength and preconsolidation pressure are key parameters in describing the characteristics of soft clays. The two parameters both reflect the clay’s structure and state of stress, and hence empirical correlations for undrained shear strength normalized with respect to preconsolidation pressure are widely used to assess soil behavior.

3. 17. Shear Stiffness and Capacity of Joints Between Precast Wall Elements

   Master-uppsats, KTH/Betongbyggnad

   Författare :Semiha Kaya; Delvin Salim; [2017]
   Nyckelord :Non-linear finite element analysis; prefabricated concrete elements; shear stiffness;

   Sammanfattning : In this thesis an investigation of the shear stiffness and capacity of joints between pre- fabricated concrete elements regarding to different material properties is reported. Two different models of shear key joints, connected to prefabricated walls, were cre- ated in the non-linear finite element software, ATENA 3D, with the aim to estimate a realistic behaviour of the joints regarding to the external loads.

4. 18. The Metamorphic History of the Helags Mountain Area, Scandinavian Caledonides

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Sara Johansson; [2016]
   Nyckelord :Seve Nappe Complex; Scandinavian Caledonides; metamorphism; monazite geochronology; garnet;

   Sammanfattning : The Scandinavian Caledonides formed as a result of collision between the continents Baltica and Laurentia, in Silurian and Early Devonian time. The evolution of the orogen has been a topic of research since before the turn of the last century. LÄS MER

5. 19. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure

   Master-uppsats, KTH/Betongbyggnad

   Författare :Eriksson Isabell; Niklas Karlsson; [2016]
   Nyckelord :concrete; linear shear; punching shear; non-linear finite element analysis; Eurocode; Model Code; ATENA 3D; betong; skjuvning; genomstansning; icke-linjär finit-elementanalys; Eurocode; Model Code; ATENA 3D;

   Sammanfattning : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.

7. 20. Modelling Lateral Stability of Prefabricated Concrete Structures

   Uppsats för yrkesexamina på avancerad nivå, KTH/Betongbyggnad

   Författare :Caroline Lindwall; Jonas Wester; [2016]
   Nyckelord :precast; concrete; hollow core; shear key; diaphragm;

   Sammanfattning : Stability calculations of prefabricated concrete structures with help of FEM-tools demand knowledge about how the elements are related to each other. This thesis concerns how joints between building elements affect the results when modelling prefabricated concrete structures, with demarcation to joints between hollow core (HC) slabs and between solid wall elements.
