1. 1. Numerical method to investigate and assess the capacity of a damaged concrete structure : Using image analysis and advanced concrete modeling

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Zakariya Benosmane; [2022]
   Nyckelord :Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

   Sammanfattning : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. LÄS MER

3. 2. Modelling masonry spires : An investigation

   Master-uppsats, KTH/Betongbyggnad

   Författare :Dennis Lillemo; [2021]
   Nyckelord :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;

   Sammanfattning : 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. 3. Cracking in a slender concrete slab due to thermal variation

   Master-uppsats, KTH/Betongbyggnad

   Författare :Johan Mattsson; Fredrik Åman; [2019]
   Nyckelord :Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

   Sammanfattning : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. LÄS MER

5. 4. The effect of pre-stressing location on punching shear capacity of concrete flat slabs

   Master-uppsats, KTH/Betongbyggnad

   Författare :Saeed Vosoughian; [2019]
   Nyckelord :Concrete flat slabs; Concrete damage plasticity model; Eurocode 2; Nonlinear finite element analysis; Punching capacity; Pre-stressing cables;

   Sammanfattning :         Implementing pre-stressing cables is a viable option aiming at controlling deformation and cracking of concrete flat slabs in serviceability limit state. The pre-stressing cables also contribute to punching shear capacity of the slab when they are located in vicinity of the column. LÄS MER

7. 5. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

   Författare :Andreas Ekman; Christoffer Sandin; [2018]
   Nyckelord :Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

   Sammanfattning : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. LÄS MER
