1. Shear strength of prestressed concrete beams without shear reinforcement : A comparison between equations
Master-uppsats, KTH/BetongbyggnadSammanfattning : 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.

2. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : 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. LÄS MER
3. Inverkan av placering av spännkablar pågenomstansningskapacitet hos armeradebetongplattor
M1-uppsats, KTH/Byggteknik och designSammanfattning : På grund av bostadsbristen de senaste åren har byggbranschen varit tvungen att möta den höga efterfrågan på bostäder. Ett sätt att underlätta det tryck som skapats på grund av den höga efterfrågan är att rekonstruera byggnader avsedda för annan användning än bostäder till bostadshus. LÄS MER
4. Widening of The Nockeby Bridge : Methods for strengthening the torsional resistance
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : i Abstract The Nockeby Bridge, in the western part of Stockholm, is a prestressed concrete bridge with an openable swing span of steel. The bridge was built during 1970 and should now be widened with 0.5 meters on each side. The concrete bridge deck is supported by two main-beams and cross-beams are located at the position of all supports. LÄS MER
