1. Cracking and Fatigue in the Prestressed Concrete Bridge at Autio
University essay from Luleå tekniska universitet/Byggkonstruktion och brandAbstract : In early 2020, cracks were discovered on the bridge crossing the Torne River at Autio. This resulted in an investigation being launched to determine the structural state of the bridge. READ MORE

2. 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

3. Shear strength of prestressed concrete beams without shear reinforcement : A comparison between equations
University essay from KTH/BetongbyggnadAbstract : A new version of EN 1992-1-1, Eurocode 2 for Design of Concrete Structures, is under development and one of the most discussed topics is shear capacity for prestressed concrete beams without shear reinforcement, partly because shear failure occurs suddenly and can have catastrophic consequences. For the new version of Eurocode, there are a total of three proposed equations to replace the two equations that currently exist in EN 1992-1-1 for shear capacity of prestressed concrete beams without shear reinforcement.

4. Prestressed glue laminated beams reinforced with steel plates : Comparison between prestressed, reinforced and non-reinforced glue laminated beams according to the Eurocode and the Swedish annex
University essay from KTH/Bro- och stålbyggnadAbstract : The paper presents details of a numerical analysis and simplified construction of strengthened glue laminated beams. Glue laminated beams are strengthened through the use of steel reinforcements embedded between the lamellas of the beams. READ MORE

5. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system
University essay from KTH/Bro- och stålbyggnadAbstract : When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. READ MORE
