1. 1. 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

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

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

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

   Abstract : 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. READ MORE

4. 3. Investigation of cracking due to restraint forces in Swedish concrete slab frame bridges

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Robin Almen; [2016]
   Keywords : slab frame bridges; concrete cracking; crack control; restraint; restraint forces; finite element; Technology and Engineering;

   Abstract : When concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. READ MORE

5. 4. Shear cracks in reinforced concrete in serviceability limit state

   University essay from KTH/Betongbyggnad

   Author : Alexander Chemlali; Rickard Norberg; [2015]
   Keywords : Shear cracks; Serviceability limit state; Modified compression field theory; Reinforced concrete panels; Non-linear FE analysis; Wing wall; Skjuvsprickor; Bruksgränstillstånd; Modifierad tryckfältsteori; Armerade betongpaneler; Icke linjär FE-analys; Vingmur;

   Abstract : Shear cracks are formed when high oblique tensile stresses, e.g. in thin webs, exceed the tensile strength. A known example of this phenomenon is the extensive shear cracks that were found on the box-girder bridges Gröndal and Alvik, which were mainly caused by insufficient amount of shear reinforcement.

6. 5. Evaluation of a Tramway’s Track Slab in Conventionally Reinforced Concrete or Steel Fibre Concrete

   University essay from KTH/Betongbyggnad

   Author : Stavros Zioris; Alija Vranjkovina; [2015]
   Keywords : Steel fibre reinforced concrete SFRC ; conventional reinforcement; finite element;

   Abstract : The dominant reinforcement used widely for concrete structures is conventional steel bars (rebars). Nevertheless, the perpetual effort toward evolution and development could not exclude the engineering field, thus new innovative and sophisticated methods are introduced. READ MORE
