2. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage
University essay from KTH/BetongbyggnadAbstract : 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

3. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges
University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologiAbstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE

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 miljöteknologiAbstract : 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
