1. 6. Simulation of load capacity of 3D printed concrete patterns

   University essay from KTH/Betongbyggnad

   Author : Magnus Burton; Karolina Näsén; [2022]
   Keywords : ;

   Abstract : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. READ MORE

3. 7. Modelling masonry spires : An investigation

   University essay from KTH/Betongbyggnad

   Author : Dennis Lillemo; [2021]
   Keywords : Abaqus; Concrete damage plasticity; Finite element method; Limit analysis; Macro-modelling; Masonry; Masonry spire; Nonlinear material; Salisbury Cathedral; Abaqus; Concrete damage plasticity; Finita elementmetoden; Gränsanalys; Makromodellering; Murverk; Murad tornspira; Icke-linjärt material; Katedralen i Salisbury;

   Abstract : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.

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

   University essay from KTH/Betongbyggnad

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

   Abstract : 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. READ MORE

5. 9. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

   University essay from KTH/Bro- och stålbyggnad

   Author : Sicong Wei; [2020]
   Keywords : high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

   Abstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

6. 10. Development of a method for estimation of contact fatigue life in hypoid gears

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Srigiripura Sahana Vittal; [2020]
   Keywords : Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

   Abstract : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. READ MORE
