  1. 1. 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

  3. 2. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system

    University essay from KTH/Bro- och stålbyggnad

    Author : Hamad El Hamad; Furkan Tanhan; [2018]
    Keywords : Movable scaffolding system; MSS; Incremental launching; post-tension; prestress; slen- derness; box-girder; Stockholm Bypass; Movable scaffolding system; MSS; Etappvis lansering; efterspänning; förspänning; slankhet; box-girder; Förbifart Stockholm;

    Abstract : 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
