• Assessment of an existing bridge suffering from Alkali-Silica reaction 

      Myklebust, Eirik Olov (Master thesis, 2018-06)
      The first parts of the thesis contain a general literature review about damage mechanisms in concrete and how they affect the structural behavior, extended with a more in-depth review of damage due to alkali-silica reactions ...
    • Corrosion induced failures of post-tensioned bridges 

      Menga, Antonia; Kanstad, Terje; Cantero, Daniel (Report, 2022-05)
      The present report includes the results obtained from a literature survey about corrosion-induced failures of post-tensioned bridges and a few other cases of prestressed structures. The structures have been briefly described ...
    • Modellering av etteroppspente betongbruer med korrosjonsskadet spennarmering 

      Kvale, Håvard Rodahl; Opheim, Trond Jørgen (Master thesis, 2019-06)
      Etteroppspente spennarmeringssystemer gjør det mulig å bygge lange og slanke brukonstruksjoner. Etter at spennkablene er spent opp og føringsrørene fylt igjen, er det derimot vanskelig å inspisere tilstanden til spennkablene ...
    • Modelling post-tensioned structures with DIANA FEM software 

      Pinto, Gianclaudio; Cantero, Daniel (Report, 2022-05)
      This report aims at providing additional information and insights for the numerical analysis of damaged post-tensioned concrete in a finite element analysis framework. The study focuses on modelling the behaviour of ...
    • Non-linear behaviour of insufficiently grouted post-tensioned concrete members 

      Vestad, Hedvig; Vestad, Magnus (Master thesis, 2021-06)
      The purpose of this master thesis was to investigate the structural effects of insufficiently grouted post tensioned concrete members. This was carried out by performing non¬linear analyses in the Finite element analysis ...
    • Numerical investigations of damaged post-tension systems and their structural effect on bridges 

      Cantero, Daniel; Terje Kanstad (Report, 2022-05)
      This study provides additional knowledge about the structural consequences of damaged PT systems, with particular focus on the presence of voids in the duct. The work consists of two distinct parts. The first part is a ...
