1. FE-Modelling of Composite Girder tests
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE

2. Study of demolition processes for prestressed concrete bridges: Kalix bridge
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Bridges in Sweden are getting older and some of them are reaching their designed life span. With an older generation of bridges, the need for a good understanding of demolition processes increase. The Kalix bridge is planned to be demolished and will be used as a case study in this thesis.

3. Strengthening of non-composite bridges by Partial Composite Action
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

4. 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

5. 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
