1. 1. Punching shear in concrete flat slabs supported on slender edge steel columns

   Master-uppsats, KTH/Betongbyggnad

   Författare :Pasha Jalal; Jose Andres Perez; [2020]
   Nyckelord :Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

   Sammanfattning : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. LÄS MER

3. 2. Shear cracks in reinforced concrete in serviceability limit state

   Master-uppsats, KTH/Betongbyggnad

   Nyckelord :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;

   Sammanfattning : 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.
