  1. 1. Smart design and production planning for drying of concrete slabs in high-rise buildings

    University essay from KTH/Hållbara byggnader

    Author : Jawad Farkouh; [2021]
    Keywords : ;

    Abstract : The Swedish concrete industry is struggling to improve the design of the concrete mixturesand produce new types of binders to reduce the negative effects on the environment due tothe relatively high carbon dioxide emissions during the manufacturing process. Theseaccelerated efforts create new challenges for the construction companies due to the lack ofknowledge about the moisture performance of these new concrete mixtures and the impactson the drying process of the concrete slabs, where the concrete drying process is oftencritical to the project schedule.

  3. 2. Modeling of moisture-induced deformations and stresses in cross-laminated timber and timber-concrete composite floors

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Marcus Johansson; [2021]
    Keywords : abaqus; numerical modeling; moisture content; relative humidity; cross-laminated timber; timber-concrete composite; finite element; Technology and Engineering;

    Abstract : Korslimmat trä är ett tämligen nytt material, bestående av korslagda lager av brädor. Produkten tillåter nya byggmetoder och kan ses som ett grönare alternativ till stål och betong. Dess uppbyggnad gör det mer robust och mindre beroende av träets varierande egenskaper för olika geometriska dimensioner. READ MORE

  4. 3. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage

    University essay from KTH/Betongbyggnad

    Author : Sidra Akbar; Mathias Carlie; [2021]
    Keywords : Balanced cantilever bridges; box girder cross-section; concrete; non-uniform creep and shrinkage; Bažant’s B4 model; Eurocode 2; long-term deformations; finite element analysis; Freivorbau broar; lådtvärsnitt; betong; ojämnkrypningoch krympning; BažantsB4 modell; Eurokod 2; långtidsdeformationer; finita element analys;

    Abstract : Balanced cantilever bridges have historically experienced excessive deformations. Previous researchsuggeststhat the cause may be due to differential thickness in the box girder cross-section and underestimation of creep and shrinkage. READ MORE

  5. 4. 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

  6. 5. Investeringskostnader i spannmålsanläggningar : jämförelse av olika nybyggnationer

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Kim Jakobsson; Erik Knutsson; [2019]
    Keywords : spannmålslagring; torkanläggning; investering; lagring; spannmålshantering;

    Abstract : Ett stort steg inom lantbruksbranschen är att bygga för att lagra spannmålen själv, istället för att skicka iväg direkt vid skörd. Detta gör det möjligt att vänta med att sälja sina varor och där av få ett bättre pris, samtidigt som det underlättar själva skördearbetet (Kasten & Dhuyvetter 1999). READ MORE
